GPRC5D

ALIASES

G-protein coupled receptor family C group 5 member D

G protein-coupled receptor class C group 5 member D (GPRC5D) is a gene expressed in the hair follicle and malignant bone marrow plasma cells.1 G protein-coupled receptor proteins are cell surface receptors located in the plasma membrane. Activation of the protein occurs when it binds to an external signaling molecule, which causes a conformational change and triggers an interaction between the protein and an available G protein.2
