General annotation (Comments)
| Function | Transcriptional coactivator of the p300/CBP-mediated trancription complex. Enhances SMAD-mediated transcription by strengthening the functional link between the DNA-binding SMAD transcription factors and the p300/CBP transcription coactivator complex. Stimulates estrogen-dependent transactivation activity mediated by estrogen receptors signaling; stabilizes the interaction of estrogen receptor ESR1 and histone acetyltransferase EP300. Positively regulates TGF-beta signaling through its association with the SMAD/p300/CBP-mediated transcriptional coactivator complex. Induces transcription from estrogen-responsive promoters and protection against cell death. Potentiates EGR2-mediated transcriptional activation activity from the ERBB2 promoter. Acts as an inhibitor of osteoblastic mineralization through a cAMP-dependent parathyroid hormone receptor signaling. May play a role in pigmentation of melanocytes. Associates with chromatin to the estrogen-responsive TGF-alpha promoter region in a estrogen-dependent manner. Ref.8 Ref.9 Ref.13 |
| Subunit structure | Interacts (via C-terminus) with CREBBP. Interacts with EGR2 By similarity. Homodimer. Binds to RBM14. Interacts (via N-terminus) with HSPA8; the interaction suppresses the association of CITED1 with p300/CBP and SMAD-mediated transcription transactivation. Interacts (via C-terminus) with TOX3 (via HGM box); the interaction increases estrogen-response element (ERE)-dependent transcription and protection against cell death. Interacts with ESR1; the interaction occurs in a estrogen-dependent manner By similarity. Interacts (unphosphorylated form preferentially and via C-terminus) with EP300. Ref.7 Ref.8 Ref.9 Ref.10 Ref.11 Ref.13 |
| Subcellular location | Nucleus. Cytoplasm. Note: Shuttles between the nucleus and the cytoplasm by a nuclear export signal and (NES) in a CRM1-dependent manner. Ref.11 |
| Tissue specificity | Expressed only in melanocytes and testis. |
| Induction | Up-regulated by GPR39 in neuronal cells. Ref.13 |
| Post-translational modification | Phosphorylated. Phosphorylation changes in a cell cycle-dependent manner and reduces its transcriptional coactivator activity. Ref.11 |
| Sequence similarities | Belongs to the CITED family. |
| Sequence caution | The sequence N30508 differs from that shown. Reason: Frameshift at position 67. |
