这个基因编码的蛋白质是一种转录共加压因子，通过DNA结合蛋白与启动子区相连。编码的蛋白质可以与几种不同的II类组蛋白脱乙酰酶相互作用来抑制转录。已经发现了两个编码不同亚型的转录变体。[由RefSeq提供，2010年5月]
The protein encoded by this gene is a transcriptional corepressor that is found tethered to promoter regions by DNA-binding proteins. The encoded protein can interact with several different class II histone deacetylases to repress transcription. Two transcript variants encoding different isoforms have been found for this gene.
