Function

Tyrp1 is a melanocyte-specific gene product involved in melanin synthesis. While mouse Tyrp1 possesses dihydroxyindole carboxylic acid oxidase activity, the function in human melanocytes is less clear. In addition to its role in melanin synthesis, Tyrp1 is involved in stabilizing of tyrosinase protein and modulating its catalytic activity. Tyrp1 is also involved in maintenance of melanosome structure and affects melanocyte proliferation and melanocyte cell death.[3]

Clinical significance

Mutations in the mouse Tyrp1 gene are associated with brown pelage and in the human TYRP1 gene with oculocutaneous albinism type 3 (OCA3).[3] An allele of TYRP1 common in Solomon Islanders results in blond hair. Although the phenotype is similar to Northern European blond hair, this allele is not found in Europeans.[4][5]

Regulation

The expression of TYRP1 is regulated by the microphthalmia-associated transcription factor (MITF).[6][7]

Interactions

TYRP1 has been shown to interact with GIPC1.[8]
