This gene encodes a member of the G-protein coupled receptor 1 family of proteins. The encoded cell surface receptor is activated through proteolytic cleavage of its extracellular amino terminus, resulting in a new amino terminus that acts as a tethered ligand that binds to an extracellular loop domain. Activation of the receptor has been shown to stimulate vascular smooth muscle relaxation, dilate blood vessels, increase blood flow, and lower blood pressure. This protein is also important in the inflammatory response, as well as innate and adaptive immunity. [provided by RefSeq, Jun 2016]
Forensic Context
A study in rhesus macaques identified the F2RL1 as a shared upregulated differentially expressed gene between rhesus and pediatric/adult human hypertrophic cardiomyopathy [Rivas et al. DOI:10.1038/s41598-024-82770-4], while separate research in human chronic wound inflammation indicated increased melanocytes in pressure sore wounds may promote inflammation through the cathepsin G-F2RL1 interaction as part of the PARs signaling pathway [Cheng et al. DOI:10.1093/burnst/tkae043].
