c-Src was the first proto-oncogenic non-receptor tyrosine kinase characterized in human. The Src family is composed of nine members in vertebrates, including c-Src, Yes, Fgr, Yrk, Fyn, Lyn, Hck, Lck, and Blk. Src-family kinases transduce signals that are involved in the control of a variety of cellular processes, including proliferation, differentiation, motility, and adhesion. Src-family kinases contain an N-terminal cell membrane anchor followed by SH3 and SH2 domains. The activity of c-Src is regulated by tyrosine phosphorylation at multiple sites. Tyrosine 418 is autophosphorylated following c-Src activation. Tyrosine 215 in the SH2 domain of c-Src is phosphorylated following growth factor receptor activation. Both Tyr-215 and Tyr-418 phosphorylation increases tyrosine kinase activity, while phosphorylation of Tyr-530 downregulates c-Src kinase activity. Thus, tyrosine phosphorylation of c-Src is critical for regulating its kinase activity.

Western blot analysis of mouse SYF cells transformed with c-Src then left untreated (lanes 1, 3, & 5) or treated with pervanadate (1 mM) for 30 minutes (lanes 2, 4, & 6). The blot was probed with anti-c-Src (Tyr-215) (lanes 1 & 2), anti-c-Src (N-terminal region) (lanes 3 & 4), and anti-c-Src (Tyr-530) (lanes 5 & 6).
Western blot analysis of A431 cells treated with pervanadate (1 mM) for 30 minutes (20 µg/lane). The Blot was probed with anti-c-Src (Tyr-215) in the presence of no blocking peptide (lane 1), phospho-c-Src (Tyr-215) peptide (lane 2), unrelated phospho-β-Catenin (Tyr-142) peptide (lane 3), or BSA conjugated to phospho-tyrosine (lane 4). Peptides and BSA were used at 1 µg/ml.
