    LRP: role in vascular wall integrity and protection from atherosclerosis (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-04-12
    Description: Vascular smooth muscle cell (SMC) proliferation and migration are important events in the development of atherosclerosis. The low-density lipoprotein receptor-related protein (LRP1) mediates suppression of SMC migration induced by platelet-derived growth factor (PDGF). Here we show that LRP1 forms a complex with the PDGF receptor (PDGFR). Inactivation of LRP1 in vascular SMCs of mice causes PDGFR overexpression and abnormal activation of PDGFR signaling, resulting in disruption of the elastic layer, SMC proliferation, aneurysm formation, and marked susceptibility to cholesterol-induced atherosclerosis. The development of these abnormalities was reduced by treatment with Gleevec, an inhibitor of PDGF signaling. Thus, LRP1 has a pivotal role in protecting vascular wall integrity and preventing atherosclerosis by controlling PDGFR activation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boucher, Philippe -- Gotthardt, Michael -- Li, Wei-Ping -- Anderson, Richard G W -- Herz, Joachim -- GM 52016/GM/NIGMS NIH HHS/ -- HL20948/HL/NHLBI NIH HHS/ -- HL63762/HL/NHLBI NIH HHS/ -- NS43408/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2003 Apr 11;300(5617):329-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Molecular Genetics, University of Texas Southwestern Medical Center, 5323 Harry Hines Boulevard, Dallas, TX 75390-9046, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12690199" target="_blank"〉PubMed〈/a〉

    OSBP is a cholesterol-regulated scaffolding protein in control of ERK 1/2 activation (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-03-05
    Description: Oxysterol-binding protein (OSBP) is the founding member of a family of sterol-binding proteins implicated in vesicle transport, lipid metabolism, and signal transduction. Here, OSBP was found to function as a cholesterol-binding scaffolding protein coordinating the activity of two phosphatases to control the extracellular signal-regulated kinase (ERK) signaling pathway. Cytosolic OSBP formed a approximately 440-kilodalton oligomer with a member of the PTPPBS family of tyrosine phosphatases, the serine/threonine phosphatase PP2A, and cholesterol. This oligomer had dual specific phosphatase activity for phosphorylated ERK (pERK). When cell cholesterol was lowered, the oligomer disassembled and the level of pERK rose. The oligomer also disassembled when exposed to oxysterols. Increasing the amount of OSBP oligomer rendered cells resistant to the effects of cholesterol depletion and decreased the basal level of pERK. Thus, cholesterol functions through its interaction with OSBP outside of membranes to regulate the assembly of an oligomeric phosphatase that controls a key signaling pathway in the cell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wang, Ping-Yuan -- Weng, Jian -- Anderson, Richard G W -- GM 52016/GM/NIGMS NIH HHS/ -- HL 20948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 2005 Mar 4;307(5714):1472-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390-9039, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15746430" target="_blank"〉PubMed〈/a〉

    Integrins regulate Rac targeting by internalization of membrane domains (2004)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2004-02-07
    Description: Translocation of the small GTP-binding protein Rac1 to the cell plasma membrane is essential for activating downstream effectors and requires integrin-mediated adhesion of cells to extracellular matrix. We report that active Rac1 binds preferentially to low-density, cholesterol-rich membranes, and specificity is determined at least in part by membrane lipids. Cell detachment triggered internalization of plasma membrane cholesterol and lipid raft markers. Preventing internalization maintained Rac1 membrane targeting and effector activation in nonadherent cells. Regulation of lipid rafts by integrin signals may regulate the location of membrane domains such as lipid rafts and thereby control domain-specific signaling events in anchorage-dependent cells.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉del Pozo, Miguel A -- Alderson, Nazilla B -- Kiosses, William B -- Chiang, Hui-Hsien -- Anderson, Richard G W -- Schwartz, Martin A -- GM52016/GM/NIGMS NIH HHS/ -- HL 20948/HL/NHLBI NIH HHS/ -- R01 GM47214/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Feb 6;303(5659):839-42.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, Scripps Research Institute, 10550 North Torrey Pines Road, La Jolla, CA 92037, USA. mdelpozo@scripps.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14764880" target="_blank"〉PubMed〈/a〉

    A role for lipid shells in targeting proteins to caveolae, rafts, and other lipid domains (2002)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2002-06-08
    Description: The surface membrane of cells is studded with morphologically distinct regions, or domains, like microvilli, cell-cell junctions, and coated pits. Each of these domains is specialized for a particular function, such as nutrient absorption, cell-cell communication, and endocytosis. Lipid domains, which include caveolae and rafts, are one of the least understood membrane domains. These domains are high in cholesterol and sphingolipids, have a light buoyant density, and function in both endocytosis and cell signaling. A major mystery, however, is how resident molecules are targeted to lipid domains. Here, we propose that the molecular address for proteins targeted to lipid domains is a lipid shell.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Richard G W -- Jacobson, Ken -- New York, N.Y. -- Science. 2002 Jun 7;296(5574):1821-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Cell Biology, University of Texas Southwestern Medical Center, Dallas, TX 75390-9039, USA. richard.anderson@utsouthwestern.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/12052946" target="_blank"〉PubMed〈/a〉

    Assembly of clathrin-coated pits onto purified plasma membranes (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-05-01
    Description: During receptor-mediated endocytosis, coated pits invaginate to form coated vesicles, clathrin and associated proteins dissociate from the vesicle membrane, and these proteins form new coated pits at the cell surface. As a means of elucidating molecular mechanisms that govern the function of coated pits, the assembly phase of this cycle was reconstituted by incubating purified membranes that were treated to remove endogenous coated pits with cytoplasm extracted from cultured cells. The in vitro assembly of coated pits on these membranes satisfactorily mimics many features of coated pit formation in the intact cell. These studies indicate that: the membranes contain a limited number of coated pit assembly sites that bind clathrin with high affinity; the half-time for assembly is 5 minutes both at 4 degrees C and 37 degrees C; during assembly, proteins with molecular sizes of 180, 110, and 36 kilodaltons are recruited to the plasma membrane; and assembly is not dependent on adenosine triphosphate, but this nucleotide triggers a temperature-dependent loss of coated pits that are assembled in the absence of adenosine triphosphate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Moore, M S -- Mahaffey, D T -- Brodsky, F M -- Anderson, R G -- HL 20948/HL/NHLBI NIH HHS/ -- New York, N.Y. -- Science. 1987 May 1;236(4801):558-63.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2883727" target="_blank"〉PubMed〈/a〉

    TIR domains of plant immune receptors are NAD+-cleaving enzymes that promote cell death (2019)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2019
    Description: 〈p〉Plant nucleotide-binding leucine-rich repeat (NLR) immune receptors activate cell death and confer disease resistance by unknown mechanisms. We demonstrate that plant Toll/interleukin-1 receptor (TIR) domains of NLRs are enzymes capable of degrading nicotinamide adenine dinucleotide in its oxidized form (NAD〈sup〉+〈/sup〉). Both cell death induction and NAD〈sup〉+〈/sup〉 cleavage activity of plant TIR domains require known self-association interfaces and a putative catalytic glutamic acid that is conserved in both bacterial TIR NAD〈sup〉+〈/sup〉-cleaving enzymes (NADases) and the mammalian SARM1 (sterile alpha and TIR motif containing 1) NADase. We identify a variant of cyclic adenosine diphosphate ribose as a biomarker of TIR enzymatic activity. TIR enzymatic activity is induced by pathogen recognition and functions upstream of the genes 〈i〉enhanced disease susceptibility 1〈/i〉 (〈i〉EDS1〈/i〉) and 〈i〉N requirement gene 1〈/i〉 (〈i〉NRG1〈/i〉), which encode regulators required for TIR immune function. Thus, plant TIR-NLR receptors require NADase function to transduce recognition of pathogens into a cell death response.〈/p〉
