General annotation (Comments)

Function	Transcriptional coactivator for steroid receptors and nuclear receptors. Coactivator of the steroid binding domain (AF-2) but not of the modulating N-terminal domain (AF-1). Required with NCOA1 to control energy balance between white and brown adipose tissues.
Subunit structure	Present in a complex containing CARM1 and EP300/P300, and interacts with CARM1 and NR3C2 By similarity. Present in a complex containing NCOA3, IKKA, IKKB, IKBKG and CREBBP. Interacts with HIF1A, NCOA1, APEX and NR3C1. Interacts with CASP8AP2 and TTLL5/STAMP.
Subcellular location	Nucleus.
Post-translational modification	Phosphorylated upon DNA damage, probably by ATM or ATR By similarity.
Involvement in disease	Chromosomal aberrations involving NCOA2 may be a cause of acute myeloid leukemias. Inversion inv(8)(p11;q13) generates the MYST3-NCOA2 oncogene, which consists of the N-terminus part of MYST3/MOZ and the C-terminus part of NCOA2/TIF2. MYST3-NCOA2 binds to CREBBP and disrupts its function in transcription activation.
Sequence similarities	Belongs to the SRC/p160 nuclear receptor coactivator family. Contains 1 basic helix-loop-helix (bHLH) domain. Contains 1 PAS (PER-ARNT-SIM) domain.
