Autophosphorylation is required for high kinase activity and efficient transformation ability of proteins encoded by host range alleles of v-src.

Journal of virology - 1 Nov 1994

Woods K M, Verderame M F

Abstract excerpt

pp60v-src is a nonreceptor protein tyrosine kinase that can transform both chicken and rodent fibroblasts. The src homology 2 (SH2) domain of this protein serves a critical role in the regulation of protein tyrosine kinase activity. The host range proteins pp60v-src-L, which contains a deletion of a highly conserved residue (Phe-172) in the SH2 domain, and pp60v-src-PPP, which contains a change from a Leu to a...
