GPR161
GPR161 (G protein-coupled receptor 161) is a gene. In the public catalogues the evidence so far is association rather than a proven role. Tied to Medulloblastoma. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.
Biology
G protein-coupled receptor that acts as a key inhibitor of the smoothened signalling pathway in primary cilia. Inhibits the smoothened signalling pathway in absence of hedgehog (DHH, IHH or SHH) by promoting formation of the transcription repressor form of GLI2 and GLI3 transcription factors. GPR161 activation triggers signalling via guanine nucleotide-binding protein G(s)/GNAS, mediating activation of adenylate cyclase activity and production of cAMP. Increased cAMP levels activate PKA, promoting PKA-dependent processing of GLI2 and GLI3 transcription factors, leading to formation of transcription repressor GLI2R and GLI3R, which repress expression of target genes. GPR161 also activates PKA by acting as a PKA-anchoring protein, which directly associates with type I PKA regulatory subunits (PRKAR1A and/or PRKAR1B), recruiting PKA followed by PKA-dependent processing of GLI2 and GLI3 transcription factors. In presence of hedgehog, GPR161 is removed from primary cilia by smoothened (SMO), preventing its activity and allowing activation of the smoothened signalling. Location: Cell projection, cilium membrane; Cell membrane (UniProt). Locus 1q24.2 (HGNC).
