Smoothened signal transduction is promoted by G protein-coupled receptor kinase 2.
(Mol Cell Biol, 2006-10)
Deregulation of the Sonic hedgehog pathway has been implicated in an increasing number of human cancers. In this pathway, the seven-transmembrane (7TM) signaling protein Smoothened regulates cellular proliferation ...
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 ...
Identification of the endophilins (SH3p4/p8/p13) as novel binding partners for the beta1-adrenergic receptor.
(Proc Natl Acad Sci U S A, 1999-10-26)
Several G-protein coupled receptors, such as the beta1-adrenergic receptor (beta1-AR), contain polyproline motifs within their intracellular domains. Such motifs in other proteins are known to mediate protein-protein interactions ...
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 ...
beta-Arrestin1 modulates lymphoid enhancer factor transcriptional activity through interaction with phosphorylated dishevelled proteins.
(Proc Natl Acad Sci U S A, 2001-12-18)
One aspect of the function of the beta-arrestins is to serve as scaffold or adapter molecules coupling G-protein coupled receptors (GPCRs) to signal transduction pathways distinct from traditional second messenger pathways. ...
