Predicted to enable methionine-tRNA ligase activity. Predicted to be involved in several processes, including RNA metabolic process; cellular response to growth factor stimulus; and positive regulation of transcription of nucleolar large rRNA by RNA polymerase I. Part of aminoacyl-tRNA synthetase multienzyme complex. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease axonal type 2U. Orthologous to human MARS1 (methionyl-tRNA synthetase 1). [provided by Alliance of Genome Resources, Apr 2022]
