    Description: The CD4 and CD8 T cell receptor accessory molecules can both be isolated from T lymphocytes in association with p56lck, a membrane-associated, cytoplasmic tyrosine protein kinase that is expressed exclusively in lymphoid cells. The enzymatic activity of p56lck may therefore be regulated by CD4 and CD8 and be important in antigen-induced T cell activation. Exposure of human T cells and some mouse T cells to the tumor promoter 12-O-tetradecanoyl phorbol-13-acetate (TPA), an activator of protein kinase C, caused the dissociation of p56lck and CD4. Activation of protein kinase C may therefore interrupt regulation of p56lck by CD4 and alter the ability of p56lck to interact with polypeptide substrates. In contrast, exposure of cells to TPA did not cause dissociation of p56lck and CD8. Regulation of p56lck by CD4 may therefore differ from regulation by CD8.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hurley, T R -- Luo, K -- Sefton, B M -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):407-9.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular Biology and Virology Laboratory, Salk Institute, San Diego, CA 92138.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2787934" target="_blank"〉PubMed〈/a〉

    Description: A 47-kilodalton neutrophil cytosol factor (NCF-47k), required for activation of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase superoxide (O2-.) production, is absent in most patients with autosomal recessive chronic granulomatous disease (AR-CGD). NCF-47k cDNAs were cloned from an expression library. The largest clone predicted a 41.9-kD protein that contained an arginine and serine-rich COOH-terminal domain with potential protein kinase C phosphorylation sites. A 33-amino acid segment of NCF-47k shared 49% identity with ras p21 guanosine triphosphatase activating protein. Recombinant NCF-47k restored O2-. -producing activity to AR-CGD neutrophil cytosol in a cell-free assay. Production of active recombinant NCF-47k will enable functional regions of this molecule to be mapped.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lomax, K J -- Leto, T L -- Nunoi, H -- Gallin, J I -- Malech, H L -- New York, N.Y. -- Science. 1989 Jul 28;245(4916):409-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bacterial Diseases Section, National Institute of Allergy and Infectious Diseases, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2547247" target="_blank"〉PubMed〈/a〉

    Description: The nitrogen regulatory (NtrC) protein of enteric bacteria, which binds to sites that have the properties of transcriptional enhancers, is known to activate transcription by a form of RNA polymerase that contains the NtrA protein (sigma 54) as sigma factor (referred to as sigma 54-holoenzyme). In the presence of adenosine triphosphate, the NtrC protein catalyzes isomerization of closed recognition complexes between sigma 54-holoenzyme and the glnA promoter to open complexes in which DNA in the region of the transcription start site is locally denatured. NtrC is not required subsequently for maintenance of open complexes or initiation of transcription.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Popham, D L -- Szeto, D -- Keener, J -- Kustu, S -- GM38361/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 3;243(4891):629-35.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Microbiology and Immunology, University of California, Berkley 94720.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2563595" target="_blank"〉PubMed〈/a〉

    Description: Inositol phospholipid-specific phospholipase C is the enzyme that generates phosphoinositide-derived messenger molecules. Mammalian cells contain at least five immunologically distinct phospholipase C enzymes that appear to be separate gene products. Complete amino acid sequences of four of these isozymes have been established. The overall sequence similarity is surprisingly low for enzymes catalyzing the same chemical reaction: three of them show limited amino acid sequence similarity to each other in two narrow regions, and the fourth enzyme is completely different. The diversity in primary structure together with different regional and cellular expression of the isozymes suggests that each isozyme has a defined function in processing the physiological response of different cell types to a variety of external stimuli and that each is regulated differently.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rhee, S G -- Suh, P G -- Ryu, S H -- Lee, S Y -- New York, N.Y. -- Science. 1989 May 5;244(4904):546-50.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Biochemistry, National Heart, Lung, and Blood Institute, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2541501" target="_blank"〉PubMed〈/a〉

    Description: Complementary DNAs for the beta subunit of the dihydropyridine-sensitive calcium channel of rabbit skeletal muscle were isolated on the basis of peptide sequences derived from the purified protein. The deduced primary structure is without homology to other known protein sequences and is consistent with the beta subunit being a peripheral membrane protein associated with the cytoplasmic aspect of the sarcolemma. The protein contains sites that might be expected to be preferentially phosphorylated by protein kinase C and guanosine 3',5'-monophosphate-dependent protein kinase. A messenger RNA for this protein appears to be expressed in brain.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ruth, P -- Rohrkasten, A -- Biel, M -- Bosse, E -- Regulla, S -- Meyer, H E -- Flockerzi, V -- Hofmann, F -- New York, N.Y. -- Science. 1989 Sep 8;245(4922):1115-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut fur Physiologische Chemie, Medizinische Fakultat, Homburg/Saar, Federal Republic of Germany.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2549640" target="_blank"〉PubMed〈/a〉

    Description: Activation of protein kinase C is thought to require association of the kinase with the cell membrane. It has been assumed that cellular substrates for the kinase must likewise be associated with membranes, and previous studies with membrane-associated myristoylated proteins have supported this view. It is now shown that a mutation that prevents the normal amino-terminal myristoylation of a prominent cellular substrate of protein kinase C, and appears to prevent its membrane association, does not prevent the normal phosphorylation of this protein in intact cells in response to phorbol esters. Thus, membrane association may not be required in order for protein kinase C substrates to undergo phosphorylation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Graff, J M -- Gordon, J I -- Blackshear, P J -- 2T32-GM 07171/GM/NIGMS NIH HHS/ -- AI27179/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Oct 27;246(4929):503-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute Laboratories, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2814478" target="_blank"〉PubMed〈/a〉

    Description: The human retinoblastoma gene (RB1) encodes a protein (Rb) of 105 kilodaltons that can be phosphorylated. Analysis of Rb metabolism has shown that the protein has a half-life of more than 10 hours and is synthesized at all phases of the cell cycle. Newly synthesized Rb is not extensively phosphorylated (it is "underphosphorylated") in cells in the G0 and G1 phases but is phosphorylated at multiple sites at the G1/S boundary and in S phase. HL-60 cells that were induced to terminally differentiate by various chemicals lost their ability to phosphorylate newly synthesized Rb at multiple sites when cell growth was arrested. These findings suggest that underphosphorylated Rb may restrict cell proliferation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mihara, K -- Cao, X R -- Yen, A -- Chandler, S -- Driscoll, B -- Murphree, A L -- T'Ang, A -- Fung, Y K -- 5P30CA14089/CA/NCI NIH HHS/ -- CA 44754/CA/NCI NIH HHS/ -- EY 07846/EY/NEI NIH HHS/ -- etc. -- New York, N.Y. -- Science. 1989 Dec 8;246(4935):1300-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Hematology/Oncology and Ophthalmology, Childrens Hospital of Los Angeles, CA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2588006" target="_blank"〉PubMed〈/a〉

    Description: The beta-adrenergic receptor kinase (beta-ARK), which specifically phosphorylates only the agonist-occupied form of the beta-adrenergic and closely related receptors, appears to be important in mediating rapid agonist-specific (homologous) desensitization. The structure of this enzyme was elucidated by isolating clones from a bovine brain complementary DNA library through the use of oligonucleotide probes derived from partial amino acid sequence. The beta-ARK cDNA codes for a protein of 689 amino acids (79.7 kilodaltons) with a protein kinase catalytic domain that bears greatest sequence similarity to protein kinase C and the cyclic adenosine monophosphate (cyclic AMP)--dependent protein kinase. When this clone was inserted into a mammalian expression vector and transfected into COS-7 cells, a protein that specifically phosphorylated the agonist-occupied form of the beta 2-adrenergic receptor and phosphorylated, much more weakly, the light-bleached form of rhodopsin was expressed. RNA blot analysis revealed a messenger RNA of four kilobases with highest amounts in brain and spleen. Genomic DNA blot analysis also suggests that beta-ARK may be the first sequenced member of a multigene family of receptor kinases.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Benovic, J L -- DeBlasi, A -- Stone, W C -- Caron, M G -- Lefkowitz, R J -- New York, N.Y. -- Science. 1989 Oct 13;246(4927):235-40.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, Duke University Medical Center, Durham, NC 27710.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2552582" target="_blank"〉PubMed〈/a〉

    Description: A defect in regulation of a chloride channel appears to be the molecular basis for cystic fibrosis (CF), a common lethal genetic disease. It is shown here that a chloride channel with kinetic and regulatory properties similar to those described for secretory epithelial cells is present in both T and B lymphocyte cell lines. The regulation of the channels by adenosine 3',5'-monophosphate (cAMP)-dependent protein kinase in transformed B cells from CF patients is defective. Thus, lymphocytes may be an accessible source of CF tissue for study of this defect, for cloning of the chloride channel complex, and for diagnosis of the disease.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chen, J H -- Schulman, H -- Gardner, P -- New York, N.Y. -- Science. 1989 Feb 3;243(4891):657-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Medicine, Stanford University, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2464852" target="_blank"〉PubMed〈/a〉

    Description: The molecules with which the platelet-derived growth factor (PDGF) receptor interacts to elicit the biochemical reactions responsible for cell proliferation have not been identified. Antisera directed against specific PDGF receptor peptides coprecipitated a phosphatidylinositol (PI) kinase and the PDGF receptor. Immunoprecipitates from PDGF-stimulated cells contained 10 to 50 times as much PI kinase as those from unstimulated cells. Mutation of the PDGF receptor by deletion of its kinase insert region resulted in a receptor markedly less effective than the wild type in eliciting cell proliferation and defective in PDGF-stimulated PI kinase, but still capable of PDGF-induced receptor autophosphorylation and phosphoinositide hydrolysis. These data show that the PDGF receptor is physically associated with a PDGF-sensitive PI kinase that is distinct from tyrosine kinase and is not required for PDGF-induced PI hydrolysis. The finding that the mutant PDGF receptor missing the kinase insert domain elicited known early biochemical responses to PDGF, but did not associate with or regulate PI kinase, suggests a novel role for the receptor-associated PI kinase in the transmission of mitogenic signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Coughlin, S R -- Escobedo, J A -- Williams, L T -- HL 32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Mar 3;243(4895):1191-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2466336" target="_blank"〉PubMed〈/a〉
