这个基因代表一个多克隆群基因。编码的蛋白质起调节基因活性的作用，可能是通过染色质修饰编码的蛋白质也可能是有丝分裂所必需的另外，还发现了编码不同亚型的剪接转录变体。[由RefSeq提供，2010年9月]
This gene represents a polycomb group gene. The encoded protein functions to regulate gene activity, likely via chromatin modification. The encoded protein may also be necessary for mitosis. Alternatively spliced transcript variants encoding different isoforms have been identified.[provided by RefSeq, Sep 2010]
