== Function ==
[https://www.uniprot.org/uniprot/GPR4_HUMAN GPR4_HUMAN] Proton-sensing G-protein coupled receptor couples to multiple intracellular signaling pathways, including GNAS/cAMP, GNAQ/phospholipase C (PLC), and GNA12/GNA13/Rho pathways (PubMed:12955148, PubMed:17462861, PubMed:20211729, PubMed:22110680). Acidosis-induced GPR4 activation increases paracellular gap formation and permeability of vascular endothelial cells through the GNA12/GNA13/Rho GTPase signaling pathway (PubMed:32058960). In the brain may mediate central respiratory sensitivity to CO(2)H(+) (By similarity).[UniProtKB:Q8BUD0]<ref>PMID:12955148</ref> <ref>PMID:17462861</ref> <ref>PMID:20211729</ref> <ref>PMID:22110680</ref> <ref>PMID:32058960</ref> [https://www.uniprot.org/uniprot/C562_ECOLX C562_ECOLX] Electron-transport protein of unknown function.
