JARID2（jumonji and AT-rich interaction domain containing 2），癌症关联基因，基因ID：3720，该基因编码一个含有Jumonji-和AT-丰富相互作用域（干旱）的蛋白质编码蛋白是一种DNA结合蛋白，起转录抑制作用该蛋白与多克隆抑制复合物2（prc2）相互作用，prc2在胚胎发育过程中调节基因表达。这种蛋白有助于PRC2复合物招募到靶基因交替剪接导致多个转录变体。这种基因突变与慢性髓系恶性肿瘤有关。[由RefSeq提供，2012年5月]This gene encodes a Jumonji- and AT-rich interaction domain (ARID)-domain-containing protein. The encoded protein is a DNA-binding protein that functions as a transcriptional repressor. This protein interacts with the Polycomb repressive complex 2 (PRC2) which plays an essential role in regulating gene expression during embryonic development. This protein facilitates the recruitment of the PRC2 complex to target genes. Alternate splicing results in multiple transcript variants. Mutations in this gene are associated with chronic myeloid malignancies. [provided by RefSeq， May 2012]。
