GPCR kinase 2 interacting protein 1 (GIT1) regulates osteoclast function and bone mass.

Abstract excerpt

G-protein-coupled receptor (GPCR) kinase 2 interacting protein-1 (GIT1) is a scaffold protein expressed in various cell types including neurons, endothelial, and vascular smooth muscle cells. The GIT1 knockout (KO) mouse has a pulmonary phenotype due to impaired endothelial function. Because GIT1 is tyrosine phosphorylated by Src kinase, we anticipated that GIT1 KO should have a bone phenotype similar to Src KO....
