Summary: Enables proline-tRNA ligase activity. Involved in prolyl-tRNA aminoacylation. Predicted to be part of aminoacyl-tRNA synthetase multienzyme complex. Predicted to be active in cytoplasm. Human ortholog(s) of this gene implicated in hypomyelinating leukodystrophy. Orthologous to human EPRS1 (glutamyl-prolyl-tRNA synthetase 1). [provided by Alliance of Genome Resources, Apr 2022]
