CC -!- FUNCTION: Regulatory protein which represses transcription and augments
CC histone deacetylase activity of HDAC1. May have a potential role in
CC tumor suppressor pathways through regulation of apoptosis. May function
CC in the assembly and/or enzymatic activity of the mSin3A corepressor
CC complex or in mediating interactions between the complex and other
CC regulatory complexes (By similarity). {ECO:0000250|UniProtKB:Q9H7L9}.
CC -!- SUBUNIT: Homodimer. Component of the SIN3 histone deacetylase (HDAC)
CC corepressor complex. Interacts with SIN3A. Interaction with SIN3B
CC enhances the interaction between SIN3B and HDAC1 to form a complex.
CC Interacts with HCFC1. Component of a mSin3A corepressor complex that
CC contains SIN3A, SAP130, SUDS3/SAP45, ARID4B/SAP180, HDAC1 and HDAC2.
CC Interacts with USP17L2; the interaction is direct (By similarity).
CC Interacts with FOXK2 (By similarity). {ECO:0000250|UniProtKB:Q9H7L9}.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000250|UniProtKB:Q9H7L9}.
CC -!- DOMAIN: The C-terminus is involved in transcriptional repression by
CC HDAC-independent mechanisms. {ECO:0000250|UniProtKB:Q9H7L9}.
CC -!- PTM: Polyubiquitinated. 'Lys-63'-polyubiquitinated SUDS3 positively
CC regulates histone deacetylation. Regulated through deubiquitination by
CC USP17L2/USP17 that cleaves 'Lys-63'-linked ubiquitin chains (By
CC similarity). {ECO:0000250|UniProtKB:Q9H7L9}.
CC -!- SIMILARITY: Belongs to the SDS3 family. {ECO:0000305}.
