該基因編碼鋅指轉錄因子gata家族的一個成員。這個家族的成員認識到gata基序存在于許多基因的啟動子中。這種蛋白被認為是調節胚胎發生、心肌分化和功能的基因，是睪丸正常發育所必需的。該基因突變與心臟間隔缺損有關。此外，基因表達的改變與幾種癌癥類型有關。選擇性剪接導致多個轉錄變體。[由RefSeq提供，2015年4月]
This gene encodes a member of the GATA family of zinc-finger transcription factors. Members of this family recognize the GATA motif which is present in the promoters of many genes. This protein is thought to regulate genes involved in embryogenesis and in myocardial differentiation and function, and is necessary for normal testicular development. Mutations in this gene have been associated with cardiac septal defects. Additionally, alterations in gene expression have been associated with several cancer types. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2015]
