Abstract excerpt
Ligand occupancy of the alphaVbeta3 integrin is required for IGF-I receptor (IGF-IR) phosphorylation of an appropriate duration and for stimulation of IGF-I actions. In vascular smooth muscle cells (SMCs), the tyrosine phosphatase SHP-2 regulates the duration of IGF-IR phosphorylation and biological actions. We determined the role of ligand occupancy of the alphaVbeta3 integrin on beta3 phosphorylation and...
