這個基因編碼的蛋白質是一種轉錄共加壓因子，通過DNA結合蛋白與啟動子區相連。編碼的蛋白質可以與幾種不同的II類組蛋白脫乙酰酶相互作用來抑制轉錄。已經發現了兩個編碼不同亞型的轉錄變體。[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.
