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.


Clinical significance

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