機能Mitochondrial outer membrane protein which regulates mitochondrial fission. Promotes the recruitment and association of the fission mediator dynamin-related protein 1 (DNM1L) to the mitochondrial surface independently of the mitochondrial fission FIS1 and MFF proteins. Regulates DNM1L GTPase activity.
組織特異性Expressed in all tissues tested with highest expression in heart and skeletal muscle.
配列類似性Belongs to the MID49/MID51 family.
細胞内局在Mitochondrion outer membrane. Colocalizes with DNM1L at mitochondrial membrane. Forms foci and rings around mitochondria.
