This gene encodes a member of the transducers of regulated cAMP response element-binding protein activity family of transcription coactivators. These proteins promote the transcription of genes targeted by the cAMP response element-binding protein, and therefore play an important role in many cellular processes. Under basal conditions the encoded protein is phosphorylated by AMP-activated protein kinase or the salt-inducible kinases and is sequestered in the cytoplasm. Upon activation by elevated cAMP or calcium, the encoded protein translocates to the nucleus and increases target gene expression. Single nucleotide polymorphisms in this gene may increase the risk of type 2 diabetes. A pseudogene of this gene is located on the long arm of chromosome 5.

Interaction

Binds, as a tetramer, through its N-terminal region, with the bZIP domain of CREB1 (PubMed:15454081). 'Arg-314' in the bZIP domain of CREB1 is essential for this interaction (PubMed:15454081). Interaction, via its C-terminal, with TAF4, enhances recruitment of TAF4 to CREB1 (PubMed:15454081). Interacts with SIK2 (PubMed:15454081). Interacts with 14-3-3 proteins, YWHAB and YWHAG (PubMed:15454081, PubMed:18626018). Interacts (probably when phosphorylated at Ser-171) with YWHAE (PubMed:30611118). Interacts with calmodulin-dependent catalytic subunit PPP3CA/calcineurin A (PubMed:15454081, PubMed:30611118). Interaction with COP1 mediates nuclear export and degradation of CRTC2 (By similarity). (Microbial infection) Interaction with the human T-cell leukemia virus type 1 (HTLV-1) Tax protein is essential for optimal transcription activation by Tax.
