Commun. 3:876-876(2012). CC -!- FUNCTION: Corepressor targeting diverse transcription regulators. CC Functions in brown adipose tissue (BAT) differentiation. Isoform 2 CC probably acts as a scaffold for specialized synapses (By similarity). CC {ECO:0000250}. CC -!- SUBUNIT: Interacts with HIPK2, ZNF217 and PNN (By similarity). CC Interacts with the transcription factors BKLF, delta EF1/AREB6/ZEB, CC EVI-1 and Friend of GATA (FOG) via the consensus motif P-X-[DNS]-L- CC [STVA]. Can form a complex with BKLF on a CACCC-box oligonucleotide. CC Can form homodimers or heterodimers of CTBP1 and CTBP2. Interacts with CC NRIP1 and WIZ. Interacts with PRDM16; represses white adipose tissue CC (WAT)-specific genes expression (By similarity). Interacts with MCRIP1 CC (By similarity). {ECO:0000250, ECO:0000250|UniProtKB:P56545}.

CC -!- PTM: Phosphorylation by HIPK2 on Ser-428 induces proteasomal CC degradation. {ECO:0000250}. CC -!- SIMILARITY: Belongs to the D-isomer specific 2-hydroxyacid CC dehydrogenase family. {ECO:0000305}.
