Predicted to enable identical protein binding activity and pyrroline-5-carboxylate reductase activity. Predicted to be involved in several processes, including L-proline biosynthetic process; negative regulation of hydrogen peroxide-induced cell death; and regulation of mitochondrial membrane potential. Predicted to be located in mitochondrion. Human ortholog(s) of this gene implicated in autosomal recessive cutis laxa type IIB and autosomal recessive cutis laxa type IIIB. Orthologous to human PYCR1 (pyrroline-5-carboxylate reductase 1). [provided by Alliance of Genome Resources, Apr 2022]
