This gene is a member of the Src family of protein tyrosine kinases (PTKs) . The encoded protein contains N-terminal sites for myristylation and palmitylation , a PTK domain , and SH2 and SH3 domains which are involved in mediating protein-protein interactions with phosphotyrosine-containing and proline-rich motifs , respectively. The protein localizes to plasma membrane ruffles , and functions as a negative regulator of cell migration and adhesion triggered by the beta-2 integrin signal transduction pathway. Infection with Epstein-Barr virus results in the overexpression of this gene. Multiple alternatively spliced variants , encoding the same protein , have been identified.
