該基因編碼一個包含sh2和sh3（SRC同源）結構域的蛋白激酶，該結構域已被證明激活ras和jun激酶信號通路并以ras依賴的方式轉化成纖維細胞。是bcr-abl酪氨酸激酶的底物，在bcr-abl的成纖維細胞轉化中起作用，可能致癌。
This gene encodes a protein kinase containing SH2 and SH3 (src homology) domains which has been shown to activate the RAS and JUN kinase signaling pathways and transform fibroblasts in a RAS-dependent fashion. It is a substrate of the BCR-ABL tyrosine kinase, plays a role in fibroblast transformation by BCR-ABL, and may be oncogenic.
