Background:  Src-family tyrosine kinases (SFK) are nonreceptor tyrosine kinases playing a critical role in mediating many cellular pathways such as proliferation, adhesion, survival, differentiation and cell motility. The structure of Src kinases is highly conserved consisting of an N-terminal membrane localization motif, a unique region, a Src homology 3 (SH3) domain, a Src homology 2 (SH2) domain, a kinase domain, and a C-terminal, regulatory tail. A phosphorylated tyrosine (Tyr 527) is bound by the SH2 domain through an intra-molecular interaction packing together with the SH3 domain the back of the kinase domain and preventing full activity of Src. Protein–tyrosine phosphatases such as PTPα displace phosphotyrosine 527 from the Src SH2 domain and mediate its dephosphorylation resulting to Src kinase activation. Loss of the negative-regulatory C-terminal segment, as occurs in v-Src, has been shown to result in increased activity and transforming potential. Activation of SRC is also achieved by direct binding of focal adhesion kinase (FAK) and CRK-associated substrate (CAS) to the SH2 domain or by interaction with numerous receptor tyrosine kinases (RTKs), such as epidermal growth factor receptor (EGFR), HER2, fibroblast growth factor receptor (FGFR), platelet-derived growth factor receptor (PDGFR), and vascular endothelial growth factor receptor (VEGFR).
