Torsin A

Torsin-1A (TorA) also known as dystonia 1 protein (DYT1) is a protein that in humans is encoded by the TOR1A gene (also known as DQ2 or DYT1).[5] TorA localizes to the endoplasmic reticulum and contiguous perinuclear space, where its ATPase activity is activated by either LULL1 or LAP1, respectively.

Function

The protein encoded by this gene is a member of the AAA family of adenosine triphosphatases (ATPases), is related to the Clp protease/heat shock family.[6]

Clinical significance

Mutations in this gene result in the autosomal dominant disorder, torsion dystonia 1.[6]
