IKZF2（IKAROS family zinc finger 2），癌症关联基因，基因ID：22807，该基因编码锌指蛋白Ikaros家族的一个成员这个蛋白家族的三个成员（Ikaros，Aiolos和Helios）是造血特异性转录因子，参与调节淋巴细胞的发育。这种蛋白质与其他Ikaros家族成员形成同型或异型二聚体，被认为主要在早期造血发育中发挥作用已发现该基因编码不同亚型的多个转录变体，但尚未确定某些变体的生物学有效性。[由RefSeq提供，2008年7月]This gene encodes a member of the Ikaros family of zinc-finger proteins. Three members of this protein family (Ikaros， Aiolos and Helios) are hematopoietic-specific transcription factors involved in the regulation of lymphocyte development. This protein forms homo- or hetero-dimers with other Ikaros family members， and is thought to function predominantly in early hematopoietic development. Multiple transcript variants encoding different isoforms have been found for this gene， but the biological validity of some variants has not been determined. [provided by RefSeq， Jul 2008]。
