Predicted to enable 1-pyrroline-5-carboxylate dehydrogenase activity; aldehyde dehydrogenase (NAD+) activity; and identical protein binding activity. Predicted to be involved in proline catabolic process to glutamate. Predicted to be located in cytosol and mitochondrion. Human ortholog(s) of this gene implicated in hyperprolinemia type 2. Orthologous to human ALDH4A1 (aldehyde dehydrogenase 4 family member A1). [provided by Alliance of Genome Resources, Apr 2022]
