TYR Recombinant Monoclonal Antibody

Uniprot Id

P14679

Target Species

Human

Target Name

TYR

Target Full Name

Tyrosinase

Target Function

This is a copper-containing oxidase that functions in the formation of pigments such as melanins and other polyphenolic compounds. Catalyzes the initial and rate limiting step in the cascade of reactions leading to melanin production from tyrosine. In addition to hydroxylating tyrosine to DOPA (3,4-dihydroxyphenylalanine), also catalyzes the oxidation of DOPA to DOPA-quinone, and possibly the oxidation of DHI (5,6-dihydroxyindole) to indole-5,6 quinone.

Target Involvement

Albinism, oculocutaneous, 1A (OCA1A); Albinism, oculocutaneous, 1B (OCA1B)

Target Subcellular Location

Melanosome membrane; Single-pass type I membrane protein. Melanosome.

Target Protein Families

Tyrosinase family

Target Research Area

Metabolism

Target Background

The enzyme encoded by this gene catalyzes the first 2 steps, and at least 1 subsequent step, in the conversion of tyrosine to melanin. The enzyme has both tyrosine hydroxylase and dopa oxidase catalytic activities, and requires copper for function. Mutations in this gene result in oculocutaneous albinism, and nonpathologic polymorphisms result in skin pigmentation variation. The human genome contains a pseudogene similar to the 3' half of this gene.
