Tor1a Gene Summary [Mouse]
Enables cytoskeletal protein binding activity; identical protein binding activity; and misfolded protein binding activity. Involved in ERAD pathway; protein localization to nucleus; and wound healing, spreading of cells. Acts upstream of or within nuclear membrane organization. Located in endoplasmic reticulum lumen and nuclear envelope. Is expressed in several structures, including alimentary system; central nervous system; hemolymphoid system gland; liver; and urinary system. Used to study focal dystonia and torsion dystonia 1. Human ortholog(s) of this gene implicated in arthrogryposis multiplex congenita-5 and torsion dystonia 1. Orthologous to human TOR1A (torsin family 1 member A).

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 Tor1a often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
