PDBsum structure summary

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]

Contents

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]
