这个基因编码的蛋白质是一种转录激活因子，它结合并激活CSF2、IL3、IL8和PRF1基因的启动子编码蛋白参与自然杀伤细胞的发育和功能，天然免疫和诱导幼稚CD8+细胞周期阻滞已经发现该基因有两个编码相同蛋白质的转录变体。[由RefSeq提供，2010年1月]
The protein encoded by this gene is a transcriptional activator that binds and activates the promoters of the CSF2, IL3, IL8, and PRF1 genes. The encoded protein is involved in natural killer cell development and function, innate immunity, and induction of cell cycle arrest in naive CD8+ cells. Two transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Jan 2010]
