| UniProt Protein Function: | SIN3A: 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. Interacts with BAZ2A, MXD3, MXD4, MBD2, NCOR1, NR4A2, REST, RLIM, SAP30, SETDB1 and SMYD2. Interacts with PHF12 in a complex composed of HDAC1, PHF12 and SAP30. Interacts with ARID4B, BRMS1L, DACH1, HCFC1, HDAC1, HDAC2, MXI1, SAP30L, SAP130, SFPQ, SUDS3 and TOPORS. Interacts with TET1; the interaction recruits SIN3A to gene promoters. Interacts with OGT (via TPRs 1-6); the interaction mediates transcriptional repression in parallel with histone deacetylase. |
