Comments
  • FUNCTION: Could be involved in the transport of tyrosine, the precursor to melanin synthesis, within the melanocyte. Regulates the pH of melanosome and the melanosome maturation. One of the components of the mammalian pigmentary system. Seems to regulate the post-translational processing of tyrosinase, which catalyzes the limiting reaction in melanin synthesis. May serve as a key control point at which ethnic skin color variation is determined. Major determinant of brown and/or blue eye color.
  • SUBCELLULAR LOCATION: Melanosome membrane; Multi-pass membrane protein.
  • ALTERNATIVE PRODUCTS: 3 named isoforms [FASTA] produced by alternative splicing.
    Name1
    Isoform IDQ04671-1
    This is the isoform sequence displayed in this entry.
    Name2
    Isoform IDQ04671-2
    Features which should be applied to build the isoform sequence: VSP_012284.
    Name3
    Isoform IDQ04671-3
    Note: No experimental confirmation available.
    Features which should be applied to build the isoform sequence: VSP_012285, VSP_012286.
  • POLYMORPHISM: Genetic variations in OCA2 are associated with skin/hair/eye pigmentation variability type 1 (SHEP1) [MIM:227220]; also known as skin/hair/eye pigmentation type 1, blue/nonblue eyes or skin/hair/eye pigmentation type 1, blue/brown eyes or skin/hair/eye pigmentation type 1, blond/brown hair or eye color, brown/blue or eye color, blue/nonblue or eye color type 3 (EYCL3) or brown eye color type 2 (BEY2) or hair color type 3 (HCL3). Hair, eye and skin pigmentation are among the most visible examples of human phenotypic variation, with a broad normal range that is subject to substantial geographic stratification. In the case of skin, individuals tend to have lighter pigmentation with increasing distance from the equator. By contrast, the majority of variation in human eye and hair color is found among individuals of European ancestry, with most other human populations fixed for brown eyes and black hair.
  • DISEASE: Defects in OCA2 are the cause of oculocutaneous albinism type 2 (OCA2) [MIM:203200]. OCA2 is an autosomal recessive form of albinism, a disorder of pigmentation in the skin, hair, and eyes. The phenotype of patients with OCA2 is typically somewhat less severe than in those with tyrosinase-deficient OCA1. There are several forms of OCA2, from typical OCA to relatively mild 'autosomal recessive ocular albinism' (AROA). OCA2 is the most prevalent type of albinism throughout the world.
  • DISEASE: The gene OCA2 is localized to chromosome 15 at 15q11.2-q12, a region associated with Prader-Willi and Angelman syndromes, suggesting that altered expression of the OCA2 gene may be responsible for the hypopygmentation phenotype exhibited by certain individuals with these disorders.
  • DISEASE: Human pigmentation, including eye color, has been associated with skin cancer risk.
  • SIMILARITY: Belongs to the SLC13A transporter (TC 2.A.47) family. P subfamily [view classification].
