Automated description from the Alliance of Genome Resources (Release 5.4.0)
Enables arginine-tRNA ligase activity. Involved in arginyl-tRNA aminoacylation. Located in mitochondrion. Part of aminoacyl-tRNA synthetase multienzyme complex. Is expressed in several structures, including alimentary system; genitourinary system; nervous system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in hypomyelinating leukodystrophy 9. Orthologous to human RARS1 (arginyl-tRNA synthetase 1).
