ID:CITE1_HUMAN DESCRIPTION: RecName: Full=Cbp/p300-interacting transactivator 1; AltName: Full=Melanocyte-specific protein 1; 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. SUBUNIT: 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. INTERACTION: P03372:ESR1; NbExp=3; IntAct=EBI-2624951, EBI-78473; SUBCELLULAR LOCATION: Nucleus. Cytoplasm. Note=Shuttles between the nucleus and the cytoplasm by a nuclear export signal and (NES) in a CRM1-dependent manner. TISSUE SPECIFICITY: Expressed only in melanocytes and testis. INDUCTION: Up-regulated by GPR39 in neuronal cells. PTM: Phosphorylated. Phosphorylation changes in a cell cycle- dependent manner and reduces its transcriptional coactivator activity. SIMILARITY: Belongs to the CITED family. SEQUENCE CAUTION: Sequence=N30508; Type=Frameshift; Positions=67;
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
