這個基因編碼的蛋白質是轉錄因子stat家族的一員。在對細胞因子和生長因子的反應中，stat家族成員被受體相關的激酶磷酸化，然后形成homo-或異二聚體，在那里它們作為轉錄激活因子轉移到細胞核。這種蛋白對于調節淋巴細胞對il12的反應和調節t輔助細胞的分化至關重要。該基因突變可能與系統性紅斑狼瘡和類風濕關節炎有關。交替剪接導致編碼相同蛋白質的多個轉錄變體。[由RefSeq提供，2011年8月]
The protein encoded by this gene is a member of the STAT family of transcription factors. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act as transcription activators. This protein is essential for mediating responses to IL12 in lymphocytes, and regulating the differentiation of T helper cells. Mutations in this gene may be associated with systemic lupus erythematosus and rheumatoid arthritis. Alternate splicing results in multiple transcript variants that encode the same protein.
