Predicted to enable protein homodimerization activity. Predicted to be involved in mitochondrial fission; positive regulation of mitochondrial fission; and protein targeting to mitochondrion. Predicted to be located in membrane and mitochondrion. Predicted to be active in mitochondrial outer membrane and peroxisome. Is expressed in female organism. Human ortholog(s) of this gene implicated in encephalopathy due to defective mitochondrial and peroxisomal fission 2. Orthologous to human MFF (mitochondrial fission factor).
