GPR18 (G-protein-coupled receptor 18) encodes a seven transmembrane G-protein-linked receptor that is highly expressed in testis and spleen. Its expression is strongest in hypothalamus, thyroid, peripheral blood leucocytes, cerebellum and brain stem. Its expression has been observed to a lesser extent in tissues associated with endocrine and immunologic/hematologic function. The gene is mapped to human chromosome 13q32. The open reading frame (ORF) encoded by this gene spans a length of 993bp. The encoded protein is 331 amino acids long.
Synonyms: Anti-G-protein coupled receptor 18; Anti-N-arachidonyl glycine receptor; Anti-NAGly receptor
Storage: -20C
Application: All Prestige Antibodies Powered by Atlas Antibodies are developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org)and as a result, are supported by the most extensive characterization in the industry. The Human Protein Atlas project can be subdivided into three efforts: Human Tissue Atlas, Cancer Atlas, and Human Cell Atlas. The antibodies that have been generated in support of the Tissue and Cancer Atlas projects have been tested by immunohistochemistry against hundreds of normal and disease tissues and through the recent efforts of the Human Cell Atlas project, many have been characterized by immunofluorescence to map the human proteome not only at the tissue level but now at the subcellular level. These images and the collection of this vast data set can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link.

Biochem Physiol Actions: The gene GPR18 encodes an orphan G-protein-coupled receptor that binds to N-arachidonylglycine (NAGly), an endogenous lipid that recruits BV-2 microglia and drives cellular migration. GPR18 is activated by phytocannabinoid, ?9-tetrahydrocannabinol (?9-THC), and by NAGly, an oxygenated metabolite of the endogenous cannabinoid anandamide. GPR18 may be involved in central nervous system and endocannabinoid system signaling. It is found to inhibit apoptosis in melanoma metastases and it also facilitates tumor cell survival. It may serve as a potential drug target in metastatic melanoma.
