General annotation (Comments)

Function	Involved in controlling the equilibrium between tubular and stacked structures in the Golgi complex. Functions in brown adipose tissue (BAT) differentiation. Corepressor targeting diverse transcription regulators such as GLIS2. Has dehydrogenase activity. Ref.2 Ref.11 Ref.19 Ref.20
Cofactor	NAD. Required for efficient interaction with E1A. Cofactor binding induces a conformation change. Ref.20
Subunit structure	Interacts with the C-terminus of adenovirus E1A protein, ELK3 and CTIP via their consensus motif P-X-[DNS]-L-[STVA]. Can form homodimers or heterodimers of CTBP1 and CTBP2. Interacts with FOXP2, HDAC4, HDAC5 and HDAC9. Interacts with GLIS2 but not GLIS1 or GLIS3. Interacts with PRDM16; represses white adipose tissue (WAT)-specific genes expression By similarity. Interacts with FOXP1, HIPK2, PNN and NRIP1. Interacts with ZFHX1B and WIZ. Interacts with Epstein-Barr virus EBNA3 and EBNA6. Interaction with non acetylated SATB1 stabalizes its attachment to DNA and promotes transcription repression. Interacts with MECOM. Ref.11 Ref.19 Ref.20 Ref.1 Ref.4 Ref.6 Ref.7 Ref.8 Ref.10 Ref.12 Ref.13 Ref.15 Ref.16
Subcellular location	Cytoplasm. Nucleus Ref.9.
Post-translational modification	The level of phosphorylation appears to be regulated during the cell cycle. Phosphorylated upon DNA damage, probably by ATM or ATR. Phosphorylation by HIPK2 on Ser-422 induces proteasomal degradation. Ref.4 Ref.10 Ref.17 ADP-ribosylated; when cells are exposed to brefeldin-A (BFA) By similarity. Sumoylation on Lys-428 is promoted by the E3 SUMO-protein ligase CBX4.
Sequence similarities	Belongs to the D-isomer specific 2-hydroxyacid dehydrogenase family.
