Journal ArticleDOI
Smoothened signal transduction is promoted by G protein-coupled receptor kinase 2.
Alison R. Meloni,Gregory B. Fralish,Patrick J. Kelly,Ali Salahpour,James K. Chen,Robert J. Wechsler-Reya,Robert J. Lefkowitz,Marc G. Caron +7 more
TL;DR: It is found that G protein-coupled receptor kinase 2 (GRK2) promotes the association between active Smoothened and β-arrestin 2, and Gli-dependent signaling, mediated by coexpression of Smoothensed and GRK2, is diminished by β-arsenin 2 knockdown with shRNA.
Journal ArticleDOI
Beta-arrestin 2 regulates zebrafish development through the hedgehog signaling pathway.
Alyson M. Wilbanks,Gregory B. Fralish,Gregory B. Fralish,Margaret L. Kirby,Larry S. Barak,Larry S. Barak,Yin-Xiong Li,Marc G. Caron,Marc G. Caron +8 more
TL;DR: It is shown that the functional knockdown of β-arrestin 2 in zebrafish embryos recapitulates the many phenotypes of Hh pathway mutants and suggests that a functional interaction betweenβ-ar Arrestin 2 and Smoothened may be critical to regulate Hh signaling in zbrafish development.
Journal ArticleDOI
Smoothened Signaling in Vertebrates Is Facilitated by a G Protein-coupled Receptor Kinase
Melanie Philipp,Gregory B. Fralish,Alison R. Meloni,Wei Chen,Alyson W. MacInnes,Larry S. Barak,Marc G. Caron +6 more
TL;DR: Results obtained in zebrafish and mice suggest that a GRK functions as a vertebrate kinase for Smoothened, promoting Hedgehog signal transduction during early development.
Journal ArticleDOI
Grk5l controls heart development by limiting mTOR signaling during symmetry breaking.
TL;DR: It is found that the zebrafish homolog of mammalian G protein-coupled receptor kinase 5 (GRK5) employs noncanonical, receptor-independent functions to secure symmetry breaking, which could implicate GRK5 as a susceptibility allele for certain cases of CHD.
Journal ArticleDOI
N-terminal Tyrosine Modulation of the Endocytic Adaptor Function of the β-Arrestins
TL;DR: It is shown that corresponding N-terminal (Y/F)VTL sequences in β-arrestin1 and -2 differentially regulate μ-adaptin binding and that these naturally occurring variations in β -arrestins may also differentially regulates the composition of the signaling complexes organized on the receptor.
