CC -!- FUNCTION: Mitochondrial outer membrane protein which regulates
CC mitochondrial fission. Promotes the recruitment and association of the
CC fission mediator dynamin-related protein 1 (DNM1L) to the mitochondrial
CC surface independently of the mitochondrial fission FIS1 and MFF
CC proteins. Regulates DNM1L GTPase activity and DNM1L oligomerization.
CC Binds ADP and can also bind GDP, although with lower affinity. Does not
CC bind CDP, UDP, ATP, AMP or GTP. Inhibits DNM1L GTPase activity in the
CC absence of bound ADP. Requires ADP to stimulate DNM1L GTPase activity
CC and the assembly of DNM1L into long, oligomeric tubules with a spiral
CC pattern, as opposed to the ring-like DNM1L oligomers observed in the
CC absence of bound ADP. Does not require ADP for its function in
CC recruiting DNM1L (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Homodimer. Interacts with DNM1L (By similarity).
CC {ECO:0000250}.
CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane {ECO:0000250};
CC Single-pass membrane protein {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the MID49/MID51 family. {ECO:0000305}.
