該基因編碼src原癌基因家族的一個非受體酪氨酸激酶，典型地參與細胞增殖和分化該蛋白在b細胞受體信號傳導和b細胞發育中起作用。該蛋白還刺激胰島素的合成和分泌，對葡萄糖作出反應，并增強一些胰腺β細胞轉錄因子的表達[由RefSeq提供，2010年8月]
This gene encodes a nonreceptor tyrosine-kinase of the src family of proto-oncogenes that are typically involved in cell proliferation and differentiation. The protein has a role in B-cell receptor signaling and B-cell development. The protein also stimulates insulin synthesis and secretion in response to glucose and enhances the expression of several pancreatic beta-cell transcription factors. [provided by RefSeq, Aug 2010]
