Biology:VIPR2
![]() Generic protein structure example |
Vasoactive intestinal peptide receptor 2 also known as VPAC2, is a G-protein coupled receptor that in humans is encoded by the VIPR2 gene.[1]
Tissue distribution
VIPR2 is expressed in the uterus, prostate, smooth muscle of the gastrointestinal tract, seminal vesicles and skin, blood vessels and thymus.[2][3] VIPR2 is also expressed in the cerebellum.[4]
Function
Vasoactive intestinal peptide (VIP) and pituitary adenylate cyclase activating polypeptide (PACAP) are homologous peptides that function as neurotransmitters and neuroendocrine hormones. While the receptors for VIP (VIRP 1 and 2) and PACAP (ADCYAP1R1) share homology, they differ in their substrate specificities and expression patterns.[1] VIPR2 transduction results in upregulation of adenylate cyclase activity.[5] Furthermore, VIPR2 mediates the anti-inflammatory effects of VIP.[6]
Research using VPAC2 knockout mice implicate it in the function of the circadian clock, growth, basal energy expenditure and male reproduction.[7][8][9][10]
VIPR2 and/or PAC1 receptor activation is involved in cutaneous active vasodilation in humans.[11]
Splice variants may modify the immunoregulatory contributions of the VIP-VIPR2 axis.[12]
VIPR2 may contribute to autoregulation and/or coupling within the suprachiasmatic nucleus (SCN) core and to control of the SCN shell.[13]
Clinical significance
VIPR2 may play a role in schizophrenia.[14]
The abnormal expression of VIPR2 messenger RNA in gallbladder tissue may play a role in the formation of gall stones and polyps.[15]
