A constitutively active mutant beta 2-adrenergic receptor is constitutively desensitized and phosphorylated.
(Proc Natl Acad Sci U S A, 1994-03-29)The beta 2-adrenergic receptor (beta 2AR) can be constitutively activated by mutations in the third intracellular loop. Whereas the wild-type receptor exists predominantly in an inactive conformation (R) in the absence of ... -
Activity of Galidesivir in a Hamster Model of SARS-CoV-2.
(Viruses, 2021-12-21)Coronavirus disease 2019 (COVID-19) has claimed the lives of millions of people worldwide since it first emerged. The impact of the COVID-19 pandemic on public health and the global economy has highlighted the medical need ... -
ARFGAP1 promotes the formation of COPI vesicles, suggesting function as a component of the coat.
(J Cell Biol, 2002-10-14)The role of GTPase-activating protein (GAP) that deactivates ADP-ribosylation factor 1 (ARF1) during the formation of coat protein I (COPI) vesicles has been unclear. GAP is originally thought to antagonize vesicle formation ... -
Beta-adrenergic receptor kinase: identification of a novel protein kinase that phosphorylates the agonist-occupied form of the receptor.
(Proc Natl Acad Sci U S A, 1986-05)Agonist-promoted desensitization of adenylate cyclase is intimately associated with phosphorylation of the beta-adrenergic receptor in mammalian, avian, and amphibian cells. However, the nature of the protein kinase(s) involved ... -
cAMP stimulates transcription of the beta 2-adrenergic receptor gene in response to short-term agonist exposure.
(Proc Natl Acad Sci U S A, 1989-07)In addition to conveying cellular responses to an effector molecule, receptors are often themselves regulated by their effectors. We have demonstrated that epinephrine modulates both the rate of transcription of the beta ... -
cDNA for the human beta 2-adrenergic receptor: a protein with multiple membrane-spanning domains and encoded by a gene whose chromosomal location is shared with that of the receptor for platelet-derived growth factor.
(Proc Natl Acad Sci U S A, 1987-01)We have isolated and sequenced a cDNA encoding the human beta 2-adrenergic receptor. The deduced amino acid sequence (413 residues) is that of a protein containing seven clusters of hydrophobic amino acids suggestive of ... -
Characterization of the murine BEK fibroblast growth factor (FGF) receptor: activation by three members of the FGF family and requirement for heparin.
(Proc Natl Acad Sci U S A, 1992-04-15)The bek gene encodes a member of the high-affinity fibroblast growth factor receptor family. The BEK/FGFR-2 receptor is a membrane-spanning tyrosine kinase with the typical features of FGF receptors. We have cloned a murine ... -
Chromosomal organization of adrenergic receptor genes.
(Proc Natl Acad Sci U S A, 1990-02)The adrenergic receptors (ARs) (subtypes alpha 1, alpha 2, beta 1, and beta 2) are a prototypic family of guanine nucleotide binding regulatory protein-coupled receptors that mediate the physiological effects of the hormone ... -
G-protein-coupled receptor genes as protooncogenes: constitutively activating mutation of the alpha 1B-adrenergic receptor enhances mitogenesis and tumorigenicity.
(Proc Natl Acad Sci U S A, 1991-12-15)The alpha 1B-adrenergic receptor (alpha 1B-ADR) is a member of the G-protein-coupled family of transmembrane receptors. When transfected into Rat-1 and NIH 3T3 fibroblasts, this receptor induces focus formation ... -
Genomic size of CENP-A domain is proportional to total alpha satellite array size at human centromeres and expands in cancer cells.
(Chromosome Res, 2011-05)Human centromeres contain multi-megabase-sized arrays of alpha satellite DNA, a family of satellite DNA repeats based on a tandemly arranged 171 bp monomer. The centromere-specific histone protein CENP-A is assembled on ... -
Inhibition of beta-adrenergic receptor kinase prevents rapid homologous desensitization of beta 2-adrenergic receptors.
(Proc Natl Acad Sci U S A, 1989-05)Homologous (agonist-specific) desensitization of beta-adrenergic receptors (beta ARs) is accompanied by and appears to require phosphorylation of the receptors. We have recently described a novel protein kinase, beta AR ... -
Molecular cloning and expression of the cDNA for the hamster alpha 1-adrenergic receptor.
(Proc Natl Acad Sci U S A, 1988-10)The cDNA for the Syrian hamster alpha 1-adrenergic receptor has been cloned with oligonucleotides corresponding to the partial amino acid sequence of the receptor protein purified from DDT1MF-2 smooth muscle cells. The deduced ... -
Phorbol esters promote alpha 1-adrenergic receptor phosphorylation and receptor uncoupling from inositol phospholipid metabolism.
(Proc Natl Acad Sci U S A, 1985-09)DDT1 MF-2 cells, which are derived from hamster vas deferens smooth muscle, contain alpha 1-adrenergic receptors (54,800 +/- 2700 sites per cell) that are coupled to stimulation of inositol phospholipid metabolism. Incubation ... -
Platelet-derived growth factor receptor association with Na(+)/H(+) exchanger regulatory factor potentiates receptor activity.
(Mol Cell Biol, 2000-11)Platelet-derived growth factor (PDGF) is a potent mitogen for many cell types. The PDGF receptor (PDGFR) is a receptor tyrosine kinase that mediates the mitogenic effects of PDGF by binding to and/or phosphorylating a variety ... -
Reciprocal in vivo regulation of myocardial G protein-coupled receptor kinase expression by beta-adrenergic receptor stimulation and blockade.
(Circulation, 1998-10-27)BACKGROUND: Impaired myocardial beta-adrenergic receptor (betaAR) signaling, including desensitization and functional uncoupling, is a characteristic of congestive heart failure. A contributing mechanism for this impairment ... -
Regions of the alpha 1-adrenergic receptor involved in coupling to phosphatidylinositol hydrolysis and enhanced sensitivity of biological function.
(Proc Natl Acad Sci U S A, 1990-04)Regions of the hamster alpha 1-adrenergic receptor (alpha 1 AR) that are important in GTP-binding protein (G protein)-mediated activation of phospholipase C were determined by studying the biological functions of mutant ... -
Single-cell microarray enables high-throughput evaluation of DNA double-strand breaks and DNA repair inhibitors.
(Cell Cycle, 2013-03-15)A key modality of non-surgical cancer management is DNA damaging therapy that causes DNA double-strand breaks that are preferentially toxic to rapidly dividing cancer cells. Double-strand break repair capacity is recognized ... -
Structural basis for receptor subtype-specific regulation revealed by a chimeric beta 3/beta 2-adrenergic receptor.
(Proc Natl Acad Sci U S A, 1993-04-15)The physiological significance of multiple G-protein-coupled receptor subtypes, such as the beta-adrenergic receptors (beta ARs), remains obscure, since in many cases several subtypes activate the same effector and utilize ...
