CREB-regulated transcription coactivator 3

Gene

CRTC3

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Transcriptional coactivator for CREB1 which activates transcription through both consensus and variant cAMP response element (CRE) sites. Acts as a coactivator, in the SIK/TORC signaling pathway, being active when dephosphorylated and acts independently of CREB1 'Ser-133' phosphorylation. Enhances the interaction of CREB1 with TAF4. Regulates the expression of specific CREB-activated genes such as the steroidogenic gene, StAR. Potent coactivator of PPARGC1A and inducer of mitochondrial biogenesis in muscle cells. Also coactivator for TAX activation of the human T-cell leukemia virus type 1 (HTLV-1) long terminal repeats (LTR).7 Publications

Interactioni

Subunit structurei

Binding, as a tetramer, through its N-terminal region, with the bZIP domain of CREB1 enhances recruitment of TAF4 to the promoter. 'Arg-314' in the bZIP domain of CREB1 is essential for this interaction (By similarity). Interaction with HTLV-1 TAX enhances its transcriptional activity. Interacts, via the N-terminal with the ankyrin repeats of BCL3, to form a complex with CREB1 on CRE and TxRE responsive elements and represses HTLV-1 LTR-mediated transcription.By similarity4 Publications
