General annotation (Comments)

Function	Transcriptional coactivator stimulating NR5A1 and ligand-dependent NR1H3/LXRA and PPARG transcriptional activities. Enhances the DNA-binding activity of ATF1, ATF2, CREB1 and NR5A1. Regulates nitric oxid synthase activity probably by sequestering calmodulin in the cytoplasm. May function in endothelial cells differentiation, hormone-induced cardiomyocytes hypertrophy and lipid metabolism. Ref.1 Ref.2 Ref.9 Ref.10
Subunit structure	Interacts with TBP and the transcription factor IID (TFIID) complex, NR5A2, NR1H3 and PPARG. Interaction with TBP is regulated by phosphorylation. Binds NR5A1, ATF1, FOS and JUN via their conserved basic region. Binding to calmodulin is regulated by calcium and phosphorylation of the IQ motif. Ref.2 Ref.9 Ref.10 Ref.8
Subcellular location	Cytoplasm. Nucleus. Note: Also nuclear upon binding to NR5A1 and treatment of cells with TPA or forskolin. Ref.2 Ref.10 Ref.8
Tissue specificity	Expressed in brain, liver, lung, kidney and heart (at protein level). Ubiquitously expressed. More abundant in heart, pancreas, liver, intestine and adipose tissues. Ref.1 Ref.2 Ref.9
Developmental stage	Expressed in fetal tissues. More abundant in kidney. Ref.1
Induction	Down-regulated by HIV type I protein TAT or phorbol ester (TPA) treatment in endothelial cells (at mRNA and protein levels). Ref.1
Domain	The IQ motif, which is involved in calmodulin binding, overlaps with the binding domain for nuclear receptors and transcription factors. Its phosphorylation probably allows a switch between the two activities of the protein By similarity.
Post-translational modification	Phosphorylated (by PKA and PKC). Ref.10 Ref.8
Sequence similarities	Contains 1 HTH cro/C1-type DNA-binding domain.
Sequence caution	The sequence CAI12698.1 differs from that shown. Reason: Erroneous gene model prediction.
