This entry represents the C-terminal domain of Dynamin-like GTPase OPA1. This protein is involved in mitochondrial fusion and inner membrane remodelling, essential for normal mitochondrial morphology by regulating the equilibrium between mitochondrial fusion and mitochondrial fission [1,2,3]. Mutations in human OPA1 cause optic atrophy [3]. This domain includes the helix bundle (HB) domains HB1 (C-terminal) and HB2 (equivalent to extreme C-terminal bundle signaling element (BSE) and to the stalk domain of dynamin-1, respectively) and the lipid-interacting stalk (LIS, equivalent to the PH domain of dynamin-1) [3].
