Protein Structure

UniProt Annotation

Function

Involved in the fragmentation of the mitochondrial network and its perinuclear clustering. Plays a minor role in the recruitment and association of the fission mediator dynamin- related protein 1 (DNM1L) to the mitochondrial surface and mitochondrial fission. May be not essential for the assembly of functional fission complexes and the subsequent membrane scission event. Can induce cytochrome c release from the mitochondrion to the cytosol, ultimately leading to apoptosis. Also mediates peroxisomal fission. {ECO:0000269PubMed:23283981}.

Subcellular Localization

Mitochondrion outer membrane; Single-pass membrane protein. Peroxisome membrane {ECO:0000250}; Single-pass membrane protein {ECO:0000250}.
