該基因編碼一個鋅指轉錄因子GATA家族的成員，該家族以它們在靶基因啟動子區域結合的一致核苷酸序列命名。編碼蛋白在調節參與造血和內分泌細胞譜系發育和增殖的基因轉錄中起著重要作用。選擇性剪接導致多個轉錄變體。
This gene encodes a member of the GATA family of zinc-finger transcription factors that are named for the consensus nucleotide sequence they bind in the promoter regions of target genes. The encoded protein plays an essential role in regulating transcription of genes involved in the development and proliferation of hematopoietic and endocrine cell lineages. Alternative splicing results in multiple transcript variants.
