Predicted to enable chromatin binding activity; protein homodimerization activity; and single-stranded DNA binding activity. Acts upstream of or within mitochondrion morphogenesis. Located in mitochondrion. Is expressed in alimentary system; brain ventricular layer; and renal cortex. Human ortholog(s) of this gene implicated in optic atrophy. Orthologous to human SSBP1 (single stranded DNA binding protein 1). [provided by Alliance of Genome Resources, Apr 2022]
