Src: Proteome Profiler Antibody Arrays

Src and other Src family protein tyrosine kinases are proto-oncogenes that play key roles in regulating cell growth and differentiation. Src family activity is regulated by tyrosine phosphorylation at two sites with opposing effects. Phosphorylation at Y419 of human Src up-regulates kinase activity, while phosphorylation at Y530 inactivates Src.
