該基因編碼一個屬于Tec激酶家族的非受體酪氨酸激酶該蛋白包含一個PH樣結構域，通過結合磷脂酰肌醇3,4,5-三磷酸（PIP3）介導膜靶向性，以及一個結合酪氨酸磷酸化蛋白和信號轉導功能的SH2結構域該蛋白參與多種信號轉導途徑，包括stat途徑，并調節多種癌細胞的分化和致瘤性。另外，已經發現該基因的剪接轉錄變體。[由RefSeq提供，2016年3月]
This gene encodes a non-receptor tyrosine kinase belonging to the Tec kinase family. The protein contains a PH-like domain, which mediates membrane targeting by binding to phosphatidylinositol 3,4,5-triphosphate (PIP3), and a SH2 domain that binds to tyrosine-phosphorylated proteins and functions in signal transduction. The protein is implicated in several signal transduction pathways including the Stat pathway, and regulates differentiation and tumorigenicity of several types of cancer cells. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Mar 2016]
