General annotation (Comments)
| Function | Transcriptional coactivator of the p300/CBP-mediated trancription complex. Acts as a bridge, linking TFAP2 transcription factors and the p300/CBP transcriptional coactivator complex in order to stimulate TFAP2-mediated transcriptional activation. Positively regulates TGF-beta signaling through its association with the SMAD/p300/CBP-mediated transcriptional coactivator complex. Stimulates the peroxisome proliferator-activated receptors PPARA transcriptional activity. Enhances estrogen-dependent transactivation mediated by estrogen receptors. Acts also as a transcriptional corepressor; interferes with the binding of the transcription factors HIF1A or STAT2 and the p300/CBP transcriptional coactivator complex. Participates in sex determination and early gonad development by stimulating transcription activation of SRY. Plays a role in controlling left-right patterning during embryogenesis; potentiates transcriptional activation of NODAL-mediated gene transcription in the left lateral plate mesoderm (LPM). Plays an essential role in differentiation of the adrenal cortex from the adrenogonadal primordium (AGP); stimulates WT1-mediated transcription activation thereby up-regulating the nuclear hormone receptor NR5A1 promoter activity. Associates with chromatin to the PITX2 P1 promoter region. Ref.6 Ref.8 Ref.9 |
| Subunit structure | Interacts (via C-terminus) with SMAD2. Interacts (via C-terminus) with SMAD3 (via MH2 domain). Interacts with LHX2 (via LIM domains). Interacts with WT1 By similarity. Interacts (via C-terminus) with EP300 (via CH1 domain); the interaction is stimulated in response to hypoxia. Interacts with PPARA. Interacts (via C-terminus) with TFAP2A, TFAP2B and TFAP2C. Ref.3 Ref.7 Ref.8 Ref.9 Ref.10 |
| Subcellular location | Nucleus. Note: Colocalizes with EP300 in dot-like structures. Ref.1 Ref.3 Ref.8 |
| Induction | By hypoxia and deferoxamine. Ref.3 |
| Involvement in disease | Ventricular septal defect 2 (VSD2) [MIM:614431]: A common form of congenital cardiovascular anomaly that may occur alone or in combination with other cardiac malformations. It can affect any portion of the ventricular septum, resulting in abnormal communications between the two lower chambers of the heart. Classification is based on location of the communication, such as perimembranous, inlet, outlet (infundibular), central muscular, marginal muscular, or apical muscular defect. Large defects that go unrepaired may give rise to cardiac enlargement, congestive heart failure, pulmonary hypertension, Eisenmenger's syndrome, delayed fetal brain development, arrhythmias, and even sudden cardiac death. Atrial septal defect 8 (ASD8) [MIM:614433]: A congenital heart malformation characterized by incomplete closure of the wall between the atria resulting in blood flow from the left to the right atria. |
| Sequence similarities | Belongs to the CITED family. |
