该基因是krueppel c2h2型锌指蛋白家族的成员，编码一个锌指转录因子，在羧基末端包含九个kruppel型锌指结构域。该蛋白位于细胞核内，参与细胞周期进程，并与组蛋白脱乙酰酶相互作用。该位点基因重排异常的特殊情况与急性早幼粒细胞白血病（apl）有关。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 Krueppel C2H2-type zinc-finger protein family and encodes a zinc finger transcription factor that contains nine Kruppel-type zinc finger domains at the carboxyl terminus. This protein is located in the nucleus, is involved in cell cycle progression, and interacts with a histone deacetylase. Specific instances of aberrant gene rearrangement at this locus have been associated with acute promyelocytic leukemia (APL). Alternate transcriptional splice variants have been characterized.
