    Description: Basic fibroblast growth factor (bFGF) participates in many processes including early developmental events, angiogenesis, wound healing, and maintenance of neuronal cell viability. A 130-kilodalton protein was isolated on the basis of its ability to specifically bind to bFGF. A complementary DNA clone was isolated with an oligonucleotide probe corresponding to determined amino acid sequences of tryptic peptide fragments of the purified protein. The putative bFGF receptor encoded by this complementary DNA is a transmembrane protein that contains three extracellular immunoglobulin-like domains, an unusual acidic region, and an intracellular tyrosine kinase domain. These domains are arranged in a pattern that is different from that of any growth factor receptor described.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lee, P L -- Johnson, D E -- Cousens, L S -- Fried, V A -- Williams, L T -- CA 21765/CA/NCI NIH HHS/ -- R01 HL32898/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1989 Jul 7;245(4913):57-60.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2544996" target="_blank"〉PubMed〈/a〉

    Description: A histone, macroH2A, nearly three times the size of conventional H2A histone, was found in rat liver nucleosomes. Its N-terminal third is 64 percent identical to a full-length mouse H2A. However, it also contains a large nonhistone region. This region has a segment that resembles a leucine zipper, a structure known to be involved in dimerization of some transcription factors. Nucleosomes containing macroH2A may have novel functions, possibly involving interactions with other nuclear proteins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pehrson, J R -- Fried, V A -- CA 06927/CA/NCI NIH HHS/ -- GM 24019/GM/NIGMS NIH HHS/ -- RR 05539/RR/NCRR NIH HHS/ -- New York, N.Y. -- Science. 1992 Sep 4;257(5075):1398-400.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Fox Chase Cancer Center, Institute for Cancer Research, Philadelphia, PA 19111.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1529340" target="_blank"〉PubMed〈/a〉

    Description: The zeta subunit of the T cell antigen receptor (TCR) exists primarily as a disulfide-linked homodimer. This receptor subunit is important in TCR-mediated signal transduction and is a substrate for a TCR-activated protein tyrosine kinase. The zeta chain was found to undergo ubiquitination in response to receptor engagement. This posttranslational modification occurred in normal T cells and tumor lines. Both nonphosphorylated and phosphorylated zeta molecules were modified, and at least one other TCR subunit, CD3 delta, was also ubiquitinated after activation of the receptor. These findings suggest an expanded role for ubiquitination in transmembrane receptor function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Cenciarelli, C -- Hou, D -- Hsu, K C -- Rellahan, B L -- Wiest, D L -- Smith, H T -- Fried, V A -- Weissman, A M -- New York, N.Y. -- Science. 1992 Aug 7;257(5071):795-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Experimental Immunology Branch, National Cancer Institute, National Institutes of Health, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/1323144" target="_blank"〉PubMed〈/a〉

    Description: Partial amino acid sequence analysis of a purified lymphocyte homing receptor demonstrates the presence of two amino termini, one of which corresponds precisely to the amino terminus of ubiquitin. This observation extends the province of this conserved polypeptide to the cell surface and leads to a proposed model of the receptor complex as a core polypeptide modified by glycosylation and ubiquitination. Independent antibodies to ubiquitin serve to identify additional cell surface species, an indication that ubiquitination of cell surface proteins may be more general. It is proposed that functional binding of lymphocytes to lymph node high endothelial venules might involve the ubiquitinated region of the receptor; if true, cell surface ubiquitin could play a more general role in cell-cell interaction and adhesion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Siegelman, M -- Bond, M W -- Gallatin, W M -- St John, T -- Smith, H T -- Fried, V A -- Weissman, I L -- AI 19512/AI/NIAID NIH HHS/ -- CA 09151/CA/NCI NIH HHS/ -- GM 31461/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):823-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003913" target="_blank"〉PubMed〈/a〉

    Publication Date: 1986-02-21
    Description: The lymphocyte cell surface receptor for the high endothelial venules (HEV's) of peripheral lymph nodes is specifically recognized by the monoclonal antibody MEL-14. Three independent complementary DNA (cDNA) clones, each of which encodes the protein ubiquitin, were detected by virtue of the expression of the MEL-14 antigenic determinant on cDNA-beta-galactosidase bacterial fusion proteins. The antigenic determinant defined by MEL-14 resides in the carboxyl terminal 13-amino-acid proteolytic peptide of ubiquitin, but is undetected in intact undenatured ubiquitin and other cellular ubiquitinated proteins. Antisera and monoclonal antibodies to ubiquitin determinants bind to the surface of both HEV-receptor positive and negative cell lines. The MEL-14-identified cDNA clones hydridize to RNA transcripts that encode tandemly repeated ubiquitins. Sequence analysis of these polyubiquitin cDNA's does not identify a leader sequence for export to the cell surface. The expression of the MEL-14 epitope of ubiquitin depends upon its local environment. The steady-state levels of expression of the ubiquitin messenger RNA's do not correlate with either the tissue derivation of the RNA or the expression of the lymphocyte HEV receptor. Regulation of the expression of the HEV receptor is not likely to reflect the transcriptional control of ubiquitin genes, but rather to reflect control of the expression of the HEV core polypeptide or its level or form of ubiquitination.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉St John, T -- Gallatin, W M -- Siegelman, M -- Smith, H T -- Fried, V A -- Weissman, I L -- AI19512/AI/NIAID NIH HHS/ -- CA 09151/CA/NCI NIH HHS/ -- GM 31461/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Feb 21;231(4740):845-50.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3003914" target="_blank"〉PubMed〈/a〉

    Description: A proteinase with high affinity for insulin has been proposed to play a role in the cellular processing of this hormone. A complementary DNA (cDNA) coding for this enzyme has been isolated and sequenced. The deduced amino acid sequence of the enzyme contained the sequences of 13 peptides derived from the isolated protein. The cDNA could be transcribed in vitro to yield a synthetic RNA that in cell-free translations produced a protein that coelectrophoresed with the native proteinase and could be immunoprecipitated with monoclonal antibodies to this enzyme. The deduced sequence of this proteinase did not contain the consensus sequences for any of the known classes of proteinases (that is, metallo, cysteine, aspartic, or serine), but it did show homology to an Escherichia coli proteinase (called protease III), which also cleaves insulin and is present in the periplasmic space. Thus, these two proteins may be members of a family of proteases that are involved in intercellular peptide signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Affholter, J A -- Fried, V A -- Roth, R A -- CA21765/CA/NCI NIH HHS/ -- DK01393/DK/NIDDK NIH HHS/ -- DK34926/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1988 Dec 9;242(4884):1415-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pharmacology, Stanford University School of Medicine, CA 94305.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3059494" target="_blank"〉PubMed〈/a〉
