Tyr Gene Summary [Mouse]

Enables protein homodimerization activity. Acts upstream of or within several processes, including melanin biosynthetic process; pigmentation; and thymus development. Located in melanosome. Is expressed in central nervous system; eye; head mesenchyme; mesenchyme derived from neural crest; and skin. Used to study buphthalmos and oculocutaneous albinism. Human ortholog(s) of this gene implicated in several diseases, including melanoma (multiple); ocular albinism 1; oculocutaneous albinism (multiple); retinoschisis; and vitiligo. Orthologous to human TYR (tyrosinase). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains

A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Tyr often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
