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.{{cite web |title=Entrez Gene: GPR143 G protein-coupled receptor 143 |url=https://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=4935}}{{cite journal | vauthors = Palmisano I, Bagnato P, Palmigiano A, Innamorati G, Rotondo G, Altimare D, Venturi C, Sviderskaya EV, Piccirillo R, Coppola M, Marigo V, Incerti B, Ballabio A, Surace EM, Tacchetti C, Bennett DC, Schiaffino MV | title = The ocular albinism type 1 protein, an intracellular G protein-coupled receptor, regulates melanosome transport in pigment cells | journal = Human Molecular Genetics | volume = 17 | issue = 22 | pages = 3487–3501 | date = November 2008 | pmid = 18697795 | pmc = 2572695 | doi = 10.1093/hmg/ddn241 }}{{cite journal | vauthors = Innamorati G, Piccirillo R, Bagnato P, Palmisano I, Schiaffino MV | title = The melanosomal/lysosomal protein OA1 has properties of a G protein-coupled receptor | journal = Pigment Cell Research | volume = 19 | issue = 2 | pages = 125–135 | date = April 2006 | pmid = 16524428 | pmc = 1459912 | doi = 10.1111/j.1600-0749.2006.00292.x }} This protein encoded by the GPR143 gene,{{cite journal | vauthors = Bassi MT, Schiaffino MV, Renieri A, De Nigris F, Galli L, Bruttini M, Gebbia M, Bergen AA, Lewis RA, Ballabio A | title = Cloning of the gene for ocular albinism type 1 from the distal short arm of the X chromosome | journal = Nature Genetics | volume = 10 | issue = 1 | pages = 13–19 | date = May 1995 | pmid = 7647783 | doi = 10.1038/ng0595-13 | s2cid = 205342065 }}{{cite journal | vauthors = Schiaffino MV, d'Addio M, Alloni A, Baschirotto C, Valetti C, Cortese K, Puri C, Bassi MT, Colla C, De Luca M, Tacchetti C, Ballabio A | title = Ocular albinism: evidence for a defect in an intracellular signal transduction system | journal = Nature Genetics | volume = 23 | issue = 1 | pages = 108–112 | date = September 1999 | pmid = 10471510 | doi = 10.1038/12715 | s2cid = 6604295 }} whose variants can lead to Ocular albinism type 1.{{cite journal | vauthors = Schiaffino MV, d'Addio M, Alloni A, Baschirotto C, Valetti C, Cortese K, Puri C, Bassi MT, Colla C, De Luca M, Tacchetti C, Ballabio A | title = Ocular albinism: evidence for a defect in an intracellular signal transduction system | journal = Nature Genetics | volume = 23 | issue = 1 | pages = 108–112 | date = September 1999 | pmid = 10471510 | doi = 10.1038/12715 | s2cid = 6604295 }}
