beta-Arrestin 1 and 2 differentially regulate heptahelical receptor signaling and trafficking.
(Proc Natl Acad Sci U S A, 2001-02-13)The two widely coexpressed isoforms of beta-arrestin (termed beta arrestin 1 and 2) are highly similar in amino acid sequence. The beta-arrestins bind phosphorylated heptahelical receptors to desensitize and target them ... -
Multiple endocytic pathways of G protein-coupled receptors delineated by GIT1 sensitivity.
(Proc Natl Acad Sci U S A, 2000-02-01)Recently, we identified a GTPase-activating protein for the ADP ribosylation factor family of small GTP-binding proteins that we call GIT1. This protein initially was identified as an interacting partner for the G protein-coupled ... -
Pollutant particles produce vasoconstriction and enhance MAPK signaling via angiotensin type I receptor.
(Environmental health perspectives, 2005-08)Exposure to particulate matter (PM) is associated with acute cardiovascular mortality and morbidity, but the mechanisms are not entirely clear. In this study, we hypothesized that PM may activate the angiotensin type 1 receptor ... -
When 7 transmembrane receptors are not G protein-coupled receptors.
(J Clin Invest, 2005-11)Classically, 7 transmembrane receptors transduce extracellular signals by coupling to heterotrimeric G proteins, although recent in vitro studies have clearly demonstrated that they can also signal via G protein-independent ...
