NCOR2（nuclear receptor corepressor 2），癌症关联基因，基因ID：9612，该基因编码一种核受体共同阻遏物，介导某些靶基因的转录沉默。编码蛋白是甲状腺激素和维甲酸受体相关共抑制因子家族的成员。该蛋白作为一个多亚单位复合物的一部分，该复合物包括组蛋白去乙酰化酶，以修饰阻止靶基因基本转录活性的染色质结构这种基因的异常表达与某些癌症有关。交替剪接导致编码不同亚型的多个转录变体。[由RefSeq提供，2011年4月]This gene encodes a nuclear receptor co-repressor that mediates transcriptional silencing of certain target genes. The encoded protein is a member of a family of thyroid hormone- and retinoic acid receptor-associated co-repressors. This protein acts as part of a multisubunit complex which includes histone deacetylases to modify chromatin structure that prevents basal transcriptional activity of target genes. Aberrant expression of this gene is associated with certain cancers. Alternate splicing results in multiple transcript variants encoding different isoforms.[provided by RefSeq， Apr 2011]。
