Melanocortin 1 receptor (MC1R) is a G protein-coupled receptor expressed in melanocytes where it plays an important role in skin pigmentation and in the UV response, and has implications in melanoma development.
Recent genomic studies have shown that mutations within components of G protein-coupled receptor (GPCR) signaling are early events associated with approximately 98% of uveal melanomas.<b>Implications:</b> This review discusses the alterations in GPCR signaling components (GNAQ and GNA11), dysregulated GPCR signaling cascades, and viable targeted therapies with the intent to provide insight into new therapeutic strategies in uveal melanoma.<i></i>.
We previously described the oncogenic properties of metabotropic glutamate receptor 1 (Grm1), a G-protein-coupled receptor in melanoma development in vivo.
The melanocortin 1 receptor, a Gs protein-coupled receptor expressed in epidermal melanocytes, is a major determinant of skin pigmentation and phototype and an important contributor to melanoma risk.
Kisspeptin (KiSS-1) gene, initially described as a melanoma metastasis suppressor gene, encodes a number of peptides (kp-54, kp-14, kp-13, kp-10), which are endogenous ligands to a G protein-coupled receptor, referred as hOT7T175 or AXOR12 or GPR54.
