A C-terminal motif found in the beta2-adrenergic receptor, P2Y1 receptor and cystic fibrosis transmembrane conductance regulator determines binding to the Na+/H+ exchanger regulatory factor family of PDZ proteins.
(Proc Natl Acad Sci U S A, 1998-07-21)The Na+/H+ exchanger regulatory factor (NHERF) binds to the tail of the beta2-adrenergic receptor and plays a role in adrenergic regulation of Na+/H+ exchange. NHERF contains two PDZ domains, the first of which is required ... -
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 ... -
A kinesin motor in a force-producing conformation.
(BMC Struct Biol, 2010-07-05)BACKGROUND: Kinesin motors hydrolyze ATP to produce force and move along microtubules, converting chemical energy into work by a mechanism that is only poorly understood. Key transitions and intermediate states in the process ... -
A modular switch for spatial Ca2+ selectivity in the calmodulin regulation of CaV channels.
(Nature, 2008-02-14)Ca2+/calmodulin-dependent regulation of voltage-gated CaV1-2 Ca2+ channels shows extraordinary modes of spatial Ca2+ decoding and channel modulation, vital for many biological functions. A single calmodulin (CaM) molecule ... -
A Peptide Uncoupling BDNF Receptor TrkB from Phospholipase Cγ1 Prevents Epilepsy Induced by Status Epilepticus.
(Neuron, 2015-11-04)The BDNF receptor tyrosine kinase, TrkB, underlies nervous system function in both health and disease. Excessive activation of TrkB caused by status epilepticus promotes development of temporal lobe epilepsy (TLE), revealing ... -
Adrenergic receptors. Models for regulation of signal transduction processes.
(Hypertension, 1990-02)Adrenergic receptors are prototypic models for the study of the relations between structure and function of G protein-coupled receptors. Each receptor is encoded by a distinct gene. These receptors are integral membrane ... -
An enzyme that inactivates the inflammatory mediator leukotriene b4 restricts mycobacterial infection.
(PLoS One, 2013)While tuberculosis susceptibility has historically been ascribed to failed inflammation, it is now known that an excess of leukotriene A4 hydrolase (LTA4H), which catalyzes the final step in leukotriene B4 (LTB4) synthesis, ... -
An Evolutionary Insertion in the Mxra8 Receptor-Binding Site Confers Resistance to Alphavirus Infection and Pathogenesis.
(Cell host & microbe, 2020-03)Alphaviruses are emerging, mosquito-transmitted RNA viruses with poorly understood cellular tropism and species selectivity. Mxra8 is a receptor for multiple alphaviruses including chikungunya virus (CHIKV). We discovered ... -
Analysis of memory B cell responses and isolation of novel monoclonal antibodies with neutralizing breadth from HIV-1-infected individuals.
(PLoS One, 2010-01-20)BACKGROUND: The isolation of human monoclonal antibodies (mAbs) that neutralize a broad spectrum of primary HIV-1 isolates and the characterization of the human neutralizing antibody B cell response to HIV-1 infection are ... -
Analysis of the mouse transcriptome for genes involved in the function of the nervous system.
(Genome Res, 2003-06)We analyzed the mouse Representative Transcript and Protein Set for molecules involved in brain function. We found full-length cDNAs of many known brain genes and discovered new members of known brain gene families, including ... -
Barnacle cement: a polymerization model based on evolutionary concepts.
(2009-11)The tenacity by which barnacles adhere has sparked a long history of scientific investigation into their adhesive mechanisms. To adhere, barnacles utilize proteinaceous cement that rapidly polymerizes and forms adhesive ... -
beta2-Adrenergic receptor regulation by GIT1, a G protein-coupled receptor kinase-associated ADP ribosylation factor GTPase-activating protein.
(Proc Natl Acad Sci U S A, 1998-11-24)G protein-coupled receptor activation leads to the membrane recruitment and activation of G protein-coupled receptor kinases, which phosphorylate receptors and lead to their inactivation. We have identified a novel ... -
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 ... -
Cloning and expression of a human kidney cDNA for an alpha 2-adrenergic receptor subtype.
(Proc Natl Acad Sci U S A, 1988-09)An alpha 2-adrenergic receptor subtype has been cloned from a human kidney cDNA library using the gene for the human platelet alpha 2-adrenergic receptor as a probe. The deduced amino acid sequence resembles the human platelet ... -
Cloning of the cDNA for the human beta 1-adrenergic receptor.
(Proc Natl Acad Sci U S A, 1987-11)Screening of a human placenta lambda gt11 library has led to the isolation of the cDNA for the human beta 1-adrenergic receptor (beta 1AR). Used as the probe was the human genomic clone termed G-21. This clone, which contains ... -
Co-evolution of a broadly neutralizing HIV-1 antibody and founder virus.
(Nature, 2013-04-25)Current human immunodeficiency virus-1 (HIV-1) vaccines elicit strain-specific neutralizing antibodies. However, cross-reactive neutralizing antibodies arise in approximately 20% of HIV-1-infected individuals, and details ... -
Conservation, duplication, and loss of the Tor signaling pathway in the fungal kingdom.
(BMC Genomics, 2010-09-23)BACKGROUND: The nutrient-sensing Tor pathway governs cell growth and is conserved in nearly all eukaryotic organisms from unicellular yeasts to multicellular organisms, including humans. Tor is the target of the immunosuppressive ... -
