该基因编码的蛋白质是dna结合蛋白同源域家族的成员。它可能调节基因表达、形态发生和分化，也可能在细胞周期的进展中发挥作用。已经识别出几个编码不同亚型的选择性剪接转录变体。[由RefSeq提供，2011年2月]
The protein encoded by this gene is a member of the homeodomain family of DNA binding proteins. It may regulate gene expression, morphogenesis, and differentiation and it may also play a role in the cell cycle progession. Several alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Feb 2011]
