Enables amino acid binding activity and proline dehydrogenase activity. Predicted to be involved in positive regulation of cell death and proline catabolic process to glutamate. Located in mitochondrion. Human ortholog(s) of this gene implicated in amino acid metabolic disorder; hyperprolinemia type 1; and schizophrenia 4. Orthologous to human PRODH (proline dehydrogenase 1). [provided by Alliance of Genome Resources, Apr 2022]
