Predicted to enable pyrroline-5-carboxylate reductase activity. Predicted to be involved in L-proline biosynthetic process and cellular response to oxidative stress. Predicted to act upstream of or within cellular amino acid biosynthetic process. Predicted to be located in mitochondrion. Is expressed in several structures, including alimentary system; brain; respiratory system; sensory organ; and skeleton. Human ortholog(s) of this gene implicated in hypomyelinating leukodystrophy 10. Orthologous to human PYCR2 (pyrroline-5-carboxylate reductase 2). [provided by Alliance of Genome Resources, Apr 2022]
