G-protein coupled receptor 143 is a protein encoded by the GPR143 gene in humans.[1][2][3]
Ocular albinism type 1 protein is a conserved integral membrane protein with seven transmembrane domains. It is expressed in the eye and epidermal melanocytes.[3]
The GPR143 gene is regulated by the Microphthalmia-associated transcription factor.[4][5]
L-DOPA is an endogenous ligand for OA1.[6]
Interactions
GPR143 has been shown to interact with GNAI1.[2]
