The function of Ensembl gene identifier ENSG00000107165 (TYRP1, tyrosinase related protein 1) is as follows. Plays a role in melanin biosynthesis (PubMed:16704458, PubMed:22556244, PubMed:23504663). Catalyzes the oxidation of 5,6- dihydroxyindole-2-carboxylic acid (DHICA) into indole-5,6-quinone-2- carboxylic acid in the presence of bound Cu(2+) ions, but not in the presence of Zn(2+) (PubMed:28661582). May regulate or influence the type of melanin synthesized (PubMed:16704458, PubMed:22556244). Also to a lower extent, capable of hydroxylating tyrosine and producing melanin (By similarity). {ECO:0000250|UniProtKB:P07147, ECO:0000269|PubMed:16704458, ECO:0000269|PubMed:22556244, ECO:0000269|PubMed:23504663, ECO:0000269|PubMed:28661582}.
