該基因編碼一種調節參與發育和凋亡的基因的轉錄因子。編碼蛋白也是一種原癌基因，并被證明與端粒酶的調節有關。該基因的一個假基因位于X染色體上。選擇性剪接導致多個轉錄變體。
This gene encodes a transcription factor which regulates genes involved in development and apoptosis. The encoded protein is also a protooncogene and shown to be involved in regulation of telomerase. A pseudogene of this gene is located on the X chromosome. Alternative splicing results in multiple transcript variants.
