    Description: The primary structure of human uromodulin, a 616-amino acid, 85-kilodalton glycoprotein with in vitro immunosuppressive properties, was determined through isolation and characterization of complementary DNA and genomic clones. The amino acid sequence encoded by one of the exons of the uromodulin gene has homology to the low-density-lipoprotein receptor and the epidermal growth factor precursor. Northern hybridization analyses demonstrate that uromodulin is synthesized by the kidney. Evidence is provided that uromodulin is identical to the previously characterized Tamm-Horsfall glycoprotein, the most abundant protein in normal human urine.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pennica, D -- Kohr, W J -- Kuang, W J -- Glaister, D -- Aggarwal, B B -- Chen, E Y -- Goeddel, D V -- New York, N.Y. -- Science. 1987 Apr 3;236(4797):83-8.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3453112" target="_blank"〉PubMed〈/a〉

    Description: The complete germline organization of the beta-chain genes of the murine T cell receptor was elucidated in order to obtain the structural basis for understanding the mechanisms of somatic DNA rearrangements. Twenty of the 22 known variable (V beta) genes are clustered within 250 kilobases of DNA 5' to the constant region (C beta) genes. These V beta genes share the same transcriptional orientation as the diversity (D beta), joining (J beta), and C beta genes, which implies that chromosomal deletion is the mechanism for most V beta to D beta-J beta rearrangements. Within this V beta cluster, the distance between the most proximal V beta gene and the D beta-J beta-C beta cluster is 320 kilobases, as determined by field-inversion gel electrophoresis. The large distance between V beta and D beta, relative to that between D beta and J beta, may have significant implications for the ordered rearrangement of the T cell receptor beta-chain genes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chou, H S -- Nelson, C A -- Godambe, S A -- Chaplin, D D -- Loh, D Y -- GM07067/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1987 Oct 23;238(4826):545-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute, Department of Medicine, Washington University School of Medicine, St. Louis, MO 63110.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2821625" target="_blank"〉PubMed〈/a〉

    Description: Ciliary neurotrophic factor (CNTF) is one of a small number of proteins with neurotrophic activities distinct from nerve growth factor (NGF). CNTF has now been purified and cloned and the primary structure of CNTF from rabbit sciatic nerve has been determined. Biologically active CNTF has been transiently expressed from a rabbit complementary DNA clone. CNTF is a neural effector without significant sequence homologies to any previously reported protein.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lin, L F -- Mismer, D -- Lile, J D -- Armes, L G -- Butler, E T 3rd -- Vannice, J L -- Collins, F -- New York, N.Y. -- Science. 1989 Nov 24;246(4933):1023-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Protein Chemistry Group, Synergen, Inc., Boulder, CO 80301.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2587985" target="_blank"〉PubMed〈/a〉

    Description: Adipsin is a serine protease that is secreted by adipocytes into the bloodstream; it is deficient in several animal models of obesity, representing a striking example of defective gene expression in this disorder. Recombinant mouse adipsin was purified and its biochemical and enzymatic properties were studied in order to elucidate the function of this protein. Activated adipsin has little or no proteolytic activity toward most substrates but has the same activity as human complement factor D, cleaving complement factor B when it is complexed with activated complement component C3. Like authentic factor D, adipsin can activate the alternative pathway of complement, resulting in red blood cell lysis. Decreased (58 to 80 percent) complement factor D activity, relative to lean controls, was observed as a common feature of several experimental models of obesity, including the ob/ob, db/db, and monosodium glutamate (MSG)-injected mouse and the fa/fa rat. These results suggest that adipsin and the alternative pathway of complement may play an unexpected but important role in the regulation of systemic energy balance in vivo.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rosen, B S -- Cook, K S -- Yaglom, J -- Groves, D L -- Volanakis, J E -- Damm, D -- White, T -- Spiegelman, B M -- DK31403/DK/NIDDK NIH HHS/ -- DK34605/DK/NIDDK NIH HHS/ -- New York, N.Y. -- Science. 1989 Jun 23;244(4911):1483-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Dana-Farber Cancer Institute, Boston, MA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2734615" target="_blank"〉PubMed〈/a〉

    Description: The RNA genome of the hepatitis delta virus (HDV) appears to be made up of two parts: a small domain with a high degree of sequence conservation and structural features likely to promote replication; plus a second, larger domain that is less conserved and encodes the delta antigen. This report focuses on one of the several sets of data that have led to the proposal of this model: the existence of a novel structural element in HDV genomic RNA. This structural element lies within the highly conserved domain of HDV RNA and may be related to the local tertiary structure previously mapped to the central conserved region of the plant viroid genome. Both elements occur in regions with no apparent coding capacity and are distinctively responsive to ultraviolet (UV) light. Transcripts containing partial and full-length genomic sequences of HDV readily undergo a UV-induced crosslinking reaction, which establishes a covalent bond between two noncontiguous segments. By locking two segments of the overall structure into place, this crosslink has permitted the unbranched, rodlike model of HDV RNA to be examined and confirmed in the portion of the RNA analyzed. The clustering of the novel tertiary structure and the recently discovered self-cleavage sites into a highly conserved, but apparently noncoding, portion of the genome defines a viroid-like domain in HDV RNA and raises questions about the possible events leading up to the association of free-living RNAs with messenger RNAs and other RNA molecules.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Branch, A D -- Benenfeld, B J -- Baroudy, B M -- Wells, F V -- Gerin, J L -- Robertson, H D -- DA-5130/DA/NIDA NIH HHS/ -- GM-28294/GM/NIGMS NIH HHS/ -- N01-AI-72623/AI/NIAID NIH HHS/ -- New York, N.Y. -- Science. 1989 Feb 3;243(4891):649-52.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Genetics, Rockefeller University, New York, NY 10021.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2492676" target="_blank"〉PubMed〈/a〉

    Description: The presence of macrophages is required for the regeneration of many cell types during wound healing. Macrophages have been reported to express a wide range of mitogenic factors and cytokines, but none of these factors has been shown in vivo to sustain all the wound-healing processes. It has been suggested that transforming growth factor-alpha (TGF-alpha) may mediate angiogenesis, epidermal regrowth, and formation of granulation tissue in vivo. Macrophages isolated from a wound site, and not exposed to cell culture conditions, expressed messenger RNA transcripts for TGF-alpha, TGF-beta, platelet-derived growth factor A-chain, and insulin-like growth factor-1. The expression of these transcripts was determined by a novel method for RNA analysis in which low numbers of mouse macrophages were isolated from wound cylinders, their RNA was purified and reverse-transcribed, and the complementary DNA was amplified in a polymerase chain reaction primed with growth factor sequence-specific primers. This single-cell RNA phenotyping procedure is rapid and has the potential for quantification, and mRNA transcripts from a single cell or a few cells can be unambiguously demonstrated, with the simultaneous analysis of several mRNA species. Macrophages from wounds expressed TGF-alpha antigen, and wound fluids contained TGF-alpha. Elicited macrophages in culture also expressed TGF-alpha transcripts and polypeptide in a time-dependent manner after stimulation with modified low-density lipoproteins and lipopolysaccharide endotoxin, which are characteristic of the activators found in injured tissues.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rappolee, D A -- Mark, D -- Banda, M J -- Werb, Z -- AR 32746/AR/NIAMS NIH HHS/ -- GM 27345/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1988 Aug 5;241(4866):708-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Laboratory of Radiobiology and Environmental Health, University of California, San Francisco 94143.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3041594" target="_blank"〉PubMed〈/a〉

    Description: A sequencing method called genomic amplification with transcript sequencing (GAWTS) is described that is based on amplification with the polymerase chain reaction (PCR). GAWTS bypasses cloning and increases the rate of sequence acquisition by at least fivefold. The method involves the attachment of a phage promoter onto at least one of the PCR primers. The segments amplified by PCR are transcribed to further increase the signal and to provide an abundance of single-stranded template for reverse transcriptase-mediated dideoxy sequencing. An end-labeled reverse transcriptase primer complementary to the desired sequence generates the additional specificity required to generate unambiguous sequence data. GAWTS can be performed on as little as a nanogram of genomic DNA. The rate of GAWTS can be increased by coamplification and cotranscription of multiple regions as illustrated by two regions of the factor IX gene. Since GAWTS lends itself well to automation, further increases in the rate of sequence acquisition can be expected.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Stoflet, E S -- Koeberl, D D -- Sarkar, G -- Sommer, S S -- New York, N.Y. -- Science. 1988 Jan 29;239(4839):491-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Molecular Biology, Mayo Clinic/Foundation, Rochester, MN 55905.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3340835" target="_blank"〉PubMed〈/a〉

    Description: The T cell antigen receptor is a multi-subunit receptor complex present on the surface of all mature and many developing T cells. It consists of clonotypic heterodimers noncovalently linked to five invariant chains that are encoded by four genes and referred to as the CD3 complex. The CD3 gamma, delta, and epsilon chains have been molecularly characterized. In this report the molecular cloning of a complementary DNA encoding the zeta chain of the murine T cell antigen receptor is described. The predicted protein sequence of the zeta chain suggests a structure distinct from those of any of the previously described receptor subunits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weissman, A M -- Baniyash, M -- Hou, D -- Samelson, L E -- Burgess, W H -- Klausner, R D -- New York, N.Y. -- Science. 1988 Feb 26;239(4843):1018-21.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Cell Biology and Metabolism Branch, National Institute of Child Health and Human Development, Bethesda, MD 20892.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/3278377" target="_blank"〉PubMed〈/a〉

    Description: Binding of antibodies to effector cells by way of receptors to their constant regions (Fc receptors) is central to the pathway that leads to clearance of antigens by the immune system. The structure and function of this important class of receptors on immune cells is addressed through the molecular characterization of Fc receptors (FcR) specific for the murine immunoglobulin G isotype. Structural diversity is encoded by two genes that by alternative splicing result in expression of molecules with highly conserved extracellular domains and different transmembrane and intracytoplasmic domains. The proteins encoded by these genes are members of the immunoglobulin supergene family, most homologous to the major histocompatibility complex molecule E beta. Functional reconstitution of ligand binding by transfection of individual FcR genes demonstrates that the requirements for ligand binding are encoded in a single gene. These studies demonstrate the molecular basis for the functional heterogeneity of FcR's, accounting for the possible transduction of different signals in response to a single ligand.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ravetch, J V -- Luster, A D -- Weinshank, R -- Kochan, J -- Pavlovec, A -- Portnoy, D A -- Hulmes, J -- Pan, Y C -- Unkeless, J C -- AI 24322/AI/NIAID NIH HHS/ -- GM 36306/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 1986 Nov 7;234(4777):718-25.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2946078" target="_blank"〉PubMed〈/a〉
