|Function||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 gluconeogenesis as a component of the LKB1/AMPK/TORC2 signaling pathway. Regulates the expression of specific 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).|
|Cellular Location||Cytoplasm. Nucleus. Note=Translocated from the nucleus to the cytoplasm on interaction of the phosphorylated form with 14-3-3 protein. In response to cAMP levels and glucagon, relocated to the nucleus|
|Tissue Location||Most abundantly expressed in the thymus. Present in both B and T-lymphocytes. Highly expressed in HEK293T cells and in insulinomas. High levels also in spleen, ovary, muscle and lung, with highest levels in muscle. Lower levels found in brain, colon, heart, kidney, prostate, small intestine and stomach. Weak expression in liver and pancreas|

CRTC2 Antibody: CRTC2, also known as TORC2 (Transducers Of Regulated cAMP Response Element-Binding (CREB)) 2 and the related protein CRTC1 are potent CREB coactivators that are exported from the nucleus in a CRM1-dependent manner via phosphorylation-dependent interactions. Studies suggest that their phosphorylation and nuclear/cytoplasmic shuttling play an important role in the regulation of gluconeogenesis by cAMP. CRTC2 is present in both B and T-lymphocytes and abundantly expressed in the thymus. Its activity is important in regulating the expression of genes involved in cellular energy metabolism while CRTC1 is essential for energy balance and fertility.
