G-protein coupled receptor 143, also known as Ocular albinism type 1 (OA1) in humans, is a conserved integral membrane protein with seven transmembrane domains and similarities with G protein-coupled receptors (GPCRs) that is expressed in the eye and epidermal melanocytes.[4][5][6] This protein encoded by the GPR143 gene,[7][8] whose variants can lead to Ocular albinism type 1.[9]
The GPR143 gene is regulated by the Microphthalmia-associated transcription factor.[10][11]
L-DOPA is an endogenous ligand for OA1.[12]
Interactions
GPR143 has been shown to interact with GNAI1.[8]
