CRTC3 Antibody (YA4340)

Nucleus; Cytoplasm

Tissue_specificity:It is primarily expressed in B cells and T cells. The highest expression level is found in lung tissue. It is also expressed in the brain, colon, heart, kidneys, ovaries, and prostate. Expression is weaker in the liver, pancreas, muscles, small intestine, spleen, and stomach.

Q6UUV7 has 2 isomers: Q6UUV7-1: 66959 Da (predicted); Q6UUV7-3: 66830 Da (predicted).
Phosphorylation/dephosphorylation states of Ser-273 are required for regulating transduction of CREB activity (By similarity). CRTCs/TORCs are inactive when phosphorylated, and active when dephosphorylated at this site (By similarity). May be phosphorylated at Ser-391 by MAPK3/ERK1 and/or MAPK1/ERK2 or by some cyclin-dependent kinases such as CDK1,CDK2 or CDK5 (PubMed:30611118). Following adenylyl cyclase activation, dephosphorylated at Ser-162 and Ser-273 resulting in its dissociation from 14-3-3 proteins probably promoting CRTC3 translocation into the nucleus (PubMed:30611118)

Binding, as a tetramer, through its N-terminal region, with the bZIP domain of CREB1 enhances recruitment of TAF4 to the promoter (PubMed:14506290). 'Arg-314' in the bZIP domain of CREB1 is essential for this interaction (PubMed:14506290). Interacts (when phosphorylated at Ser-162 and Se-273) with 14-3-3 proteins (PubMed:30611118). Interacts with YWHAE (PubMed:30611118). Interacts (when phosphorylated at Ser-391) with phosphatase PP2A catalytic subunit PPP2CA and regulatory subunits PPP2R1A and PPP2R2A (PubMed:30611118). 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 (PubMed:17644518)
