Summaries for TYRP1 Gene

Entrez Gene Summary for TYRP1 Gene

  • This gene encodes a melanosomal enzyme that belongs to the tyrosinase family and plays an important role in the melanin biosynthetic pathway. Defects in this gene are the cause of rufous oculocutaneous albinism and oculocutaneous albinism type III. [provided by RefSeq, Mar 2009]

GeneCards Summary for TYRP1 Gene

TYRP1 (Tyrosinase Related Protein 1) is a Protein Coding gene. Diseases associated with TYRP1 include Albinism, Oculocutaneous, Type Iii and Albinism. Among its related pathways are Metabolism and Wnt Signaling Pathways: beta-Catenin-independent Wnt/Ca2+ Signaling and Other Non-canonical Wnt Signaling Pathways. GO annotations related to this gene include protein homodimerization activity and oxidoreductase activity. An important paralog of this gene is DCT.

UniProtKB/Swiss-Prot for TYRP1 Gene

  • Catalyzes the 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. Also to a lower extent, capable of hydroxylating tyrosine and producing melanin.

Variants for TYRP1 Gene

Polymorphic Variants from UniProtKB/Swiss-Prot for TYRP1 Gene

Genetic variants in TYRP1 define the skin/hair/eye pigmentation variation locus 11 (SHEP11) [MIM:612271] and are responsible for variability in hair color linked to chromosome 9p23 in Melanesians. 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.

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. {ECO:0000269 PubMed:16704458, ECO:0000269 PubMed:23504663}.
