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.

Note=Chromosomal aberrations involving NCOA2 may be a cause of acute myeloid leukemias. Inversion inv(8)(p11;q13) generates the KAT6A-NCOA2 oncogene, which consists of the N-terminal part of KAT6A and the C-terminal part of NCOA2/TIF2. KAT6A-NCOA2 binds to CREBBP and disrupts its function in transcription activation.

Belongs to the SRC/p160 nuclear receptor coactivator family.
Contains 1 bHLH (basic helix-loop-helix) domain.
Contains 1 PAS (PER-ARNT-SIM) domain.

Contains four Leu-Xaa-Xaa-Leu-Leu (LXXLL) motifs. The LXXLL motifs are essential for the association with nuclear receptors and are, at least in part, functionally redundant.
The LLXXLXXXL motif is involved in transcriptional coactivation and CREBBP/CBP binding.
Contains 2 C-terminal transcription activation domains (AD1 and AD2) that can function independently.

Phosphorylated upon DNA damage, probably by ATM or ATR.
