H-2Db & B2M & TRP1 (TAPDNLGYA)

TRP1 refers to tyrosinase-related protein. TRP1 is encoded by the TYRP1 gene. It is the human homologue of the brown (b)-locus in mice, the corresponding protein of which is associated with melanogenesis and pigmentation disorders of the skin. The exact function of TRP1 is still unknown. Besides its enzymatic activity, it may also play a structural role in the melanosome. TYRP1 is involved in the production of eumelanin, but it has also been implicated in the maintenance of the ultrastructure of melanosomes, melanocyte proliferation, and apoptosis. Defects in TYRP1 are the cause of albinism oculocutaneous type 3 (OCA3).
