Target

  • Function

    Oxidation of 5,6-dihydroxyindole-2-carboxylic acid (DHICA) into indole-5,6-quinone-2-carboxylic acid. May regulate or influence the type of melanin synthesized.
  • Tissue specificity

    Pigment cells.
  • Pathway

    Pigment biosynthesis; melanin biosynthesis.
  • Involvement in disease

    Defects in TYRP1 are the cause of albinism oculocutaneous type 3 (OCA3) [MIM:203290]; also known as Rufous oculocutaneous albinism. An autosomal recessive disorder in which the biosynthesis of melanin pigment is reduced in skin, hair, and eyes. Tyrosinase activity is normal and patients have only moderate reduction of pigment. The eyes present red reflex on transillumination of the iris, dilution of color of iris, nystagmus and strabismus. Darker-skinned individuals have bright copper-red coloration of the skin and hair.
  • Sequence similarities

    Belongs to the tyrosinase family.
  • Cellular localization

    Melanosome membrane.

    Predicted band size: 61 kDa
    Observed band size: 75 kDa
    why is the actual band size different from the predicted?



    Exposure time: Lane 1: 10 seconds; Lane 2: 3 seconds.

    Blocking/Dilution buffer: 5% NFDM/TBST.

    The observed mass is greater than the predicted due to glycosylation.

    The molecular mass observed is consistent with what has been described in the literature (PMID: 21324755; PMID: 18042623;18650849).
