Target Background

G-protein coupled receptor for CRH (corticotropin-releasing factor), UCN (urocortin), UCN2 and UCN3. Has high affinity for UCN. Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and down-stream effectors, such as adenylate cyclase. Promotes the activation of adenylate cyclase, leading to increased intracellular cAMP levels.
Gene References into Functions
  1. A non-coding CRHR2 SNP rs255105, a cis-eQTL for a downstream lincRNA AC005154.6, is associated with heroin addiction. PMID: 29953524
  2. CRF2 signaling induces alterations in both the epithelium permeability and the differentiation of human colonic carcinoma cell lines. PMID: 28811708
  3. Data show that corticotropin releasing hormone receptor 2 (Crhr2) protein is abundantly expressed in the heart, and plasma Ucn2 levels were higher in patients with heart failure compared to healthy controls, indicating that endogenous Crhr2 is associated with heart failure. PMID: 28550160
  4. Taken together, our data indicate that sex shows significant interaction with genotype and Ucn1 during colitis. Human duodenal and colonic biopsies revealed that sex-specific differences exist in levels of CRF receptors and Ucn1 expression in patients with CD compared with the matched non-IBD subjects. To conclude, Ucn1 mediates sex-specific immune and cellular signaling responses via CRF2, emphasizing the need for inclus PMID: 27053649
  5. Endogenous CRF may be involved in the pathogenesis of ischemia/reperfusion-induced enteritis, possibly via the activation of peripheral CRF receptor 2 PMID: 28011950
  6. This study showed that two CRHR2 variants (rs4722999-C and rs12701020-C) in BPD subjects with sexual and physical abuse. PMID: 26182893
  7. found associations between CRHR2 genotypes and haplotypes and negative emotion in IBS patients and controls PMID: 26808377

  10. D1 and CRF2 alpha receptors are capable of heterodimerization in living cells. D1 /CRF2 alpha receptor heteromerization might account, at least in part, for the complex physiological interactions established between dopamine and CRH. PMID: 25073922
  11. no difference in placental expression between intrahepatic cholestasis of pregnancy and controls PMID: 25172671
  12. not up-regulated by labor in placenta, fetal membranes, or myometrium PMID: 25426872
  13. HSF2 element confers estrogen up-regulation of CRHR2 transcription and estrogen increases CRHR2 transcription via induction of HSF2 demethylation. PMID: 24485608
  14. Results suggest CRHR-2 variants may affect risk for PTSD in women by attenuating the stress response and reducing symptoms of the disorder. PMID: 24123648
  15. The rate and extent of homologous CRF2(a) receptor desensitization is governed by agonist-specific mechanisms affecting G protein-coupled receptor kinase phosphorylation. PMID: 23820308
  16. CRFR2 antagonist astressin-2B abrogated the effects of UCN2 on VSMCs. In conclusion, UCN2 is significantly associated with AAA and inhibits VSMC proliferation by inducing a G1 cell cycle arrest suggesting a plausible regulatory role in AAA pathogenesis PMID: 24107226
  17. The down-regulation of the CRF2 receptor in the distal/sigmoid biopsies of ulcerative colitis patients is indicative of change in CRF2 signalling associated with the process of inflammation. PMID: 23539366

  20. These findings reveal a complex interplay between the signaling molecules that allow "fine-tuning" of CRH-R2beta functional responses and regulate signal integration. PMID: 21338628
  21. nuclear translocation of Ucn along with the loss of CRFR2 in epithelial cells and microvasculature of tumoral specimens may be involved in the pathobiology of renal cell carcinoma PMID: 19437022
