abstract = {A cDNA complementary to the mRNA of the ADPIATP carrier from Neurospora crassa was identified among ordered cDNA clones by hybridizing total polyadenylated RNA to pools of 96 cDNA recombinant plasmids and subsequent cellfree translation of hybridization-selected mRNA. Further carrier cDNAs were found by colony fdter hybridization at a frequency of 0.2-0.3\%. The gene of the carrier was cloned and isolated on a 4.6-kbp EcoRl fragment of total Neurospora DNA, and the start of the mRNA was determined by Sl nuclease mapping. From the nucleotide sequence of the cDNA and the genomic DNA, the primary structure of the gene, of the mRNA and of the ADP I ATP carrier protein could be deduced. The gene occurs in a single copy in the genome and related genes are absent. It contains two short introns, and a pyrimidine-rieb promoter region. The mRNA has a 46-bp 5 1 end and a 219-bp 3 1 end. There is an open reading frame coding for the 313 amino acid residues of the Neurospora carrier protein. The amino acid sequence is homologous in 148 positions with the established primary structure of the beef heart carrier.},

To obtain more information about the physiological role of the c-src gene in cells, we have studied differentiation-dependent alterations using the human HL-60 leukaemia cell line as a model system. Induction of monocytic and granulocytic differentiation of HL-60 cells by 12-0-tetradecanoylphorbol-13-acetate (TPA) and dimethylsulfoxide (DMSO) is associated with an activation of the pp60c-src tyrosine kinase, but not with increased c-src gene expression. Control experiments exclude an interaction of TPA and DMSO themselves with the pp60c-src kinase.},

abstract = {In a study from 2011, the protein muskelin was described as a central coordinator of the retrograde transport of GABA(A) receptors in neurons. As muskelin governs the transport along actin filaments as well as microtubules, it might be the first representative of a novel class of regulators, which coordinate cargo transport across the borders of these two independent systems of transport paths and their associated motorproteins. To establish a basis for understanding the mode of operation of muskelin, the aim of this thesis was an in-depth biochemical and structural characterization of muskelin and its interaction with the GABA(A) receptor. One focus of the work was the analysis of the oligomerization of muskelin. As could be demonstrated, the oligomerization is based on two independent interactions mediated by different domains of the protein: a known interaction of the N-terminal discoidin domain with the C-terminal portion, termed head-to-tail interaction, and a dimerization of the LisH motif in muskelin that was so far neglected in the literature. For the detailed studies of both binding events, the solution of a crystal structure of a fragment of muskelin, comprising the Discoidin domain and the LisH motif, was an important basis. The fragment crystallized as a dimer, with dimerization being mediated solely by the LisH motif. Biochemical analysis corroborated that the LisH motif in muskelin serves as a dimerization element, and, moreover, showed that the C-terminal domain of the protein substantially stabilizes this dimerization. In addition, the crystal structure revealed the molecular composition of the surface of the head in the head-to-tail interaction, namely the discoidin domain. This information enabled to map the amino acids contributing to binding, which showed that the binding site of the head-to-tail interaction coincides with the generic ligand binding site of the discoidin domain. As part of the analyses, residues that are critical for LisH-dimerization and the head-to-tail binding, respectively, were identified, whose mutation specifically interfered with each of the interactions separately. These mutations allowed to investigate the interplay of these interactions during oligomerization. It could be shown that recombinant muskelin assembles into a tetramer to which both interactions, the LisH-dimerization and the head-to-tail binding, contribute independently. When one of the two interactions was disturbed, only a dimer mediated via the respective other interaction could be formed; when both interactions were disturbed, the protein was present as monomer. Furthermore, Frank Heisler in the group of Matthias Kneussel was able to show the drastic impact of an impaired LisH-dimerization on muskelin in cells using these mutations. Disturbing the LisH-dimerization led to a complete redistribution of the originally cytoplasmic muskelin to the nucleus which was accompanied by a severe impairment of its function during GABA(A) receptor transport. Following up on these results in an analysis of muskelin variants, for which alterations of the subcellular localization had been published earlier, the crucial influence of LisH-dimerization to the subcellular localization and thereby the role of muskelin in the cell was confirmed. The biochemical studies of the interaction of muskelin and the alpha1 subunit of the GABA(A) receptor demonstrated a direct binding with an affinity in the low micromolar range, which is mediated primarily by the kelch repeat domain in muskelin. For the binding site on the GABA(A) receptor, it was confirmed that the thirteen most C-terminal residues of the intracellular domain are critical for the binding of muskelin. In accordance with the strong conservation of these residues among the alpha subunits of the GABA(A) receptor, it could be shown that an interaction with muskelin in vitro is also possible for the alpha2 and alpha5 subunits. Based on the comparison of the binding sites between the homologous subunits, tentative conclusions can be drawn about the details of the binding, which may serve as a starting point for follow-up studies. This thesis thereby makes valuable contributions to the understanding of muskelin, in particular the significance of its oligomerization. It furthermore provides an experimental framework for future studies that address related topics, such as the characterization of other muskelin interaction partners, or the questions raised in this work.},

Structural data show that the human growth hormone (hGH) forms a complex with a homodimeric receptor and that hGH is a member of a class of hematopoietins possessing an antiparallel 4-a-helix bundle fold. Mutagenesis experiments suggest that electrostatic interactions may have an important influence on hormonereceptor recognition. In order to examine the specificity of hormone-receptor complexation, an analysis was made of the electrostatic potentials of hGH, interleukin-2 (IL-2), interleukin-4 (IL-4), granulocyte colony-stimulating factor (G-CSF), granulocyte-macrophage colony-stimulating factor (GM-CSF), and the hGH and IL-4 receptors. The binding surfaces of hGH and its receptor, and of IL-4 and its receptor, show complementary electrostatic potentials. The potentials of the hGH and its receptor display approximately 2-fold rotational symmetry because the receptor subunits are identical. In contrast, the potentials of GM-CSF and IL-2 Iack such symmetry, consistent with their known high affinity for hetero-oligomeric receptors. Analysis of the electrostatic potentials supports a recently proposed hetero-oligomeric model for a high-affinity IL-4 receptor and suggests a possible new receptor binding mode for G-CSF; it also provides valuable information for guiding structural and mutagenesis studies of signal-transducing proteins and their receptors.},

abstract = {Members of the RAF protein kinase family are key regulators of diverse cellular processes. The need for isoform-specific regulation is reflected by the fact that all RAFs not only display a different degree of activity but also perform isoform-specific functions at diverse cellular compartments. Protein-protein-interactions and phosphorylation events are essential for the signal propagation along the Ras-RAF-MEK-ERK cascade. More than 40 interaction partners of RAF kinases have been described so far. Two of the most important regulators of RAF activity, namely Ras and 14-3-3 proteins, are subject of this work. So far, coupling of RAF with its upstream modulator protein Ras has only been investigated using truncated versions of RAF and regardless of the lipidation status of Ras. We quantitatively analyzed the binding properties of full-length B- and C-RAF to farnesylated H-Ras in presence and absence of membrane lipids. While the isolated Ras-binding domain of RAF exhibit a high binding affinity to both, farnesylated and nonfarnesylated H-Ras, the full-length RAF kinases demonstrate crucial differences in their affinity to Ras. In contrast to C-RAF that requires carboxyterminal farnesylated H-Ras for interaction at the plasma membrane, B-RAF also binds to nonfarnesylated H-Ras in the cytosol. For identification of the potential farnesyl binding site we used several fragments of the regulatory domain of C-RAF and found that the binding of farnesylated H-Ras is considerably increased in the presence of the cysteine-rich domain of RAF. In B-RAF a sequence of 98 amino acids at the extreme N terminus enables binding of Ras independent of its farnesylation status. The deletion of this region altered Ras binding as well as kinase properties of B-RAF to resemble C-RAF. Immunofluorescence studies in mammalian cells revealed essential differences between B- and C-RAF regarding the colocalization with Ras. In conclusion, our data suggest that that B-RAF, in contrast to C-RAF, is also accessible for nonfarnesylated Ras in the cytosolic environment due to its prolonged N terminus. Therefore, the activation of B-RAF may take place both at the plasma membrane and in the cytosolic environment. Furthermore, the interaction of RAF isoforms with Ras at different subcellular sites may also be governed by the complex formation with 14-3-3 proteins. 14-3-3 adapter proteins play a crucial role in the activation of RAF kinases, but so far no information about the selectivity of the seven mammalian isoforms concerning RAF association and activation is available. We analyzed the composition of in vivo RAF/14-3-3 complexes isolated from mammalian cells with mass spectrometry and found that B-RAF associates with a greater variety of 14-3-3 proteins than C- and A-RAF. In vitro binding assays with purified proteins supported this observation since B-RAF showed highest affinity to all seven 14-3-3 isoforms, whereas C-RAF exhibited reduced affinity to some and A-RAF did not bind to the 14-3-3 isoforms epsilon, sigma, and tau. To further examine this isoform specificity we addressed the question of whether both homo- and heterodimeric forms of 14-3-3 proteins participate in RAF signaling. By deleting one of the two 14-3-3 isoforms in Saccharomyces cerevisiae we were able to show that homodimeric 14-3-3 proteins are sufficient for functional activation of B- and C-RAF. In this context, the diverging effect of the internal, inhibiting and the activating C-terminal 14-3-3 binding domain in RAF could be demonstrated. Furthermore, we unveil that prohibitin stimulates C-RAF activity by interfering with 14-3-3 at the internal binding site. This region of C-RAF is also target of phosphorylation as part of a negative feedback loop. Using tandem MS we were able to identify so far unknown phosphorylation sites at serines 296 and 301. Phosphorylation of these sites in vivo, mediated by activated ERK, leads to inhibition of C-RAF kinase activity. The relationship of prohibitin interference with 14-3-3 binding and phosphorylation of adjacent sites has to be further elucidated. Taken together, our results provide important new information on the isoform-specific regulation of RAF kinases by differential interaction with Ras and 14-3-3 proteins and shed more light on the complex mechanism of RAF kinase activation.},

One RSF plasmid directed the synthesis of all three main polypeptides of the R. sphaeroides blc1 complex: the FeS protein, cytochrome b and cytochrome c1• The FeS protein and cytochrome c1 were apparently synthesized as precursor fonns. None of the pRSF plasmids directed the synthesis of the 10-kd polypeptide found in b/c1 complex preparations. Partial sequencing of the cloned region was performed. Several sites of strong homology between R. sphaeroides and eukaryotic polypeptides of the b/c1 complex were identified. The genes encode the three b/c1 polypeptides in the order: (5') FeS protein, cytochrome b, cytochrome c1• The three genes are transcribed to give a polycistronic mRNA of 2.9 kb. This transcriptional unit has been designated the jbc operon; its coding capacity corresponds to the size of the polycistronic mRNA assuming that only the genes for the FeS protein (jbcF), cytochrome b (jbcß) and cytochrome c1 (jbcC) are present.

The c-src mRNA and its translational product are detectable at high levels in brain extracts of chicken embryos and adult chickens, whereas muscle extracts show an age-dependent decrease in the amounts of c-src-specific mRNA and pp60c-src kinase activity. In contrast, the Ievels of c-yes mRNA in brain, heart, and muscle are relatively low in early embryonic stages and increase later on to values comparable to those found for liver, while in adult animals the pattern of c-yes expression is similar to that of the c-src gene. From the close correlation between the Ievels of pp60c-src, its enzymatic activity, and its corresponding mRNA at a given stage of development and in given tissues, it appears that the expression of pp60c-src is primarily controlled at the level of transcription. It is suggested that because of the different patterns of expression, the two cellular oncogenes, c-src and c-yes, play different roles in cell proliferation during early embryonic stages as weil as in ensuing differentiation processes.},
