Predicted to enable identical protein binding activity. Predicted to be involved in cellular response to DNA damage stimulus; mitochondrial protein catabolic process; and mitophagy by induced vacuole formation. Predicted to act upstream of or within cell differentiation and spermatogenesis. Predicted to be located in mitochondrion and sperm flagellum. Predicted to be active in mitochondrial outer membrane. Orthologous to human SPATA18 (spermatogenesis associated 18). [provided by Alliance of Genome Resources, Apr 2022]
