General annotation (Comments)

Function	Regulatory protein which represses transcription and augments histone deacetylase activity of HDAC1. May have a potential role in tumor suppressor pathways By similarity. May function in the assembly and/or enzymatic activity of the mSin3A corepressor complex or in mediating interactions between the complex and other regulatory complexes. UniProtKB Q8BR65
Subunit structure	Homodimer. Component of the SIN3 histone deacetylase (HDAC) corepressor complex. Interacts with SIN3A. Interaction with SIN3B enhances the interaction between SIN3B and HDAC1 to form a complex By similarity. Interacts with HCFC1. Component of a mSin3A corepressor complex that contains SIN3A, SAP130, SUDS3/SAP45, ARID4B/SAP180, HDAC1 and HDAC2. UniProtKB Q8BR65 Ref.5
Tissue specificity	Expressed in various cancer cell ines. Ref.2
Domain	The C-terminus is involved in transcriptional repression by HDAC-independent mechanisms.
Sequence similarities	Belongs to the SDS3 family.
