Figure 2. Stimulation of torsinA ATPase activity by LAP1 or LULL1.
A) The ATPase activity of torsinA is stimulated by LAP1 or LULL1 through the formation of heterohexamers on the INM and ER membranes, respectively18, 46. B) Top-down view of the alternating torsinA-LAP1/LULL1 heterohexamer in A18, 46.
