function:Involved in the functional recruitment of the Sin3-histone deacetylase complex (HDAC) to a specific subset of N-CoR corepressor complexes. Capable of transcription repression by N-CoR. Active in deacetylating core histone octamers (when in a complex) but inactive in deacetylating nucleosomal histones.,similarity:Belongs to the SAP30 family.,subunit:Interacts with SIN3A, SIN3B, HDAC2 and NCOR1 (By similarity). Component of the histone deacetylase complex that includes at least SIN3A, HDAC1 and HDAC2. Interacts with HDAC1 and HCFC1.,tissue specificity:Expressed in all tissues tested with highest levels in pancreas, ovary, PBL, spleen and thymus; lowest levels in brain, placenta, lung and kidney.,
