這個基因是一個假定的癌基因，編碼一個屬于絲氨酸/蘇氨酸激酶亞家族的蛋白質，包含sh2樣（SRC同源2樣）結構域。該基因在8個卵巢癌細胞系中的2個和15個原發性卵巢腫瘤中的2個被擴增和過度表達。過度表達導致人導管胰腺癌亞群的惡性表型。編碼蛋白是一種普通的蛋白激酶，能夠對幾種已知的蛋白進行磷酸化。
This gene is a putative oncogene encoding a protein belonging to a subfamily of serine/threonine kinases containing SH2-like (Src homology 2-like) domains. The gene was shown to be amplified and overexpressed in 2 of 8 ovarian carcinoma cell lines and 2 of 15 primary ovarian tumors. Overexpression contributes to the malignant phenotype of a subset of human ductal pancreatic cancers. The encoded protein is a general protein kinase capable of phophorylating several known proteins.
