Protein Information (annotations from UniProt)

Database IDHIV0004403
UniProt IDQ6UUV9
Primary gene name(s)CRTC1
Synonym gene name(s)KIAA0616, MECT1, TORC1, WAMTP1
Protein nameCREB-regulated transcription coactivator 1
Protein functionTranscriptional 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 PGC1alpha 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. In the hippocampus, involved in late-phase long-term potentiation, L-LTP maintenance at the Schaffer collateral-CA1 synapses. May be required for dendritic growth of developing cortical neurons, By similarity. In concert with SIK1, regulates the light-induced entrainment of the circadian clock. In response to light stimulus, coactivates the CREB-mediated transcription of PER1 which plays an important role in the photic entrainment of the circadian clock. {ECO:0000250|UniProtKB:Q157S1, ECO:0000250|UniProtKB:Q68ED7, ECO:0000269|PubMed:23699513}.
Subcellular locationCytoplasm {ECO:0000269|PubMed:15589160}. Nucleus {ECO:0000269|PubMed:15589160}. Note=Cytoplasmic when phosphorylated by SIK or AMPK and when sequestered by 14-3-3 proteins, PubMed:16817901. Translocated to the nucleus on Ser-151 dephosphorylation, instigated by a number of factors including calcium ion and cAMP levels, PubMed:15589160. Light stimulation triggers a nuclear accumulation in the suprachiasmatic nucleus, SCN of the brain, By similarity. {ECO:0000250|UniProtKB:Q68ED7, ECO:0000269|PubMed:15589160, ECO:0000269|PubMed:16817901}.
