该基因编码的蛋白与人乳腺癌转移抑制蛋白（brms1）和哺乳动物sds3（缺陷沉默抑制蛋白3）的序列相似。该蛋白是组蛋白脱乙酰基酶复合物（HDAC）mSin3a家族的一个组成部分[由RefSeq提供，2008年7月]
The protein encoded by this gene shows sequence similarity to the human breast carcinoma metastasis suppressor (BRMS1) protein and the mammalian Sds3 (suppressor of defective silencing 3) proteins. This protein is a component of the mSin3a family of histone deacetylase complexes (HDAC). [provided by RefSeq, Jul 2008]
