该基因是髓系/淋巴系或混合系白血病（MLL）家族的一员，编码一种带有N末端PHD锌指和中心集域的蛋白质过表达的蛋白质抑制细胞周期的进展。交替转录剪接变体已经被描述[由RefSeq提供，2008年7月]
This gene is a member of the myeloid/lymphoid or mixed-lineage leukemia (MLL) family and encodes a protein with an N-terminal PHD zinc finger and a central SET domain. Overexpression of the protein inhibits cell cycle progression. Alternate transcriptional splice variants have been characterized. [provided by RefSeq, Jul 2008]
