Paxillin, a focal adhesion protein, is a substrate for several tyrosine kinases such as src, FAK, and p120BRC/ABL. The tyrosine phosphorylation of paxillin is affected by conditions that change cell-cell adhesion. This is consisent with the possibility that paxillin is involved in the regulation of cell morphology. Additionally, because of its SH3-binding domain, paxillin associates tightly with FAK and Crk in an extracellular matrix-independent manner. Although paxillin was initially detected in fibroblasts, its phosphorylation may be important during neurite extension during differentiation.
