Mammalian Sin 3 (mSin 3) is a protein closely related to the yeast SIN3 repressor protein involved in the transcriptional repression of many genes. There are two mammalian isoforms, mSin 3A and mSin 3B. Containing 4 paired amphipathic helix domains (PAH domains), mSin 3A and mSin 3B have been shown to directly interact with several other transcriptional repressor proteins including HDAC 1, HDAC 2, RbAp 46, the methyl CpG binding protein MeCP 2, the Mad/Max heterodimer, and the corepressors silencing mediator of retinoic acid & thyroid hormone receptor (SMRT) and nuclear receptor corepressor (N-CoR).

Function:Acts as a transcriptional repressor. Corepressor for REST. Interacts with MXI1 to repress MYC responsive genes and antagonize MYC oncogenic activities. Also interacts with MXD1-MAX heterodimers to repress transcription by tethering SIN3A to DNA. Acts cooperatively with OGT to repress transcription in parallel with histone deacetylation.Subunit:Interacts with ARID4B, BRMS1L, HCFC1, HDAC1, HDAC2, MXI1, SAP30L, SAP130, SFPQ and TOPORS. Interacts with OGT (via TPRs 1-6); the interaction mediates transcriptional repression in parallel with histone deacetylase (By similarity). Interacts with BAZ2A, MXD3, MXD4, MBD2, DACH1, NCOR1, NR4A2, REST, RLIM, SAP30, SETDB1, SMYD2, and SUDS3. Interacts with PHF12 in a complex composed of HDAC1, PHF12 and SAP30. Interacts with TET1; the interaction recruits SIN3A to gene promoters.Subcellular Location:Nucleus. Nucleus, nucleolus. Note=Recruited to the nucleolus by SAP30L (By similarity).Tissue Specificity:Widely expressed. Highest levels in testis, lung and thymus.Post-translational modifications:SUMO1 sumoylated by TOPORS. Probably desumoylated by SENP2 (By similarity).Similarity:Contains 3 PAH (paired amphipathic helix) domains.
