    Summary
    Predicted to enable lysine-tRNA ligase activity and tRNA binding activity. Involved in several processes, including determination of adult lifespan; positive regulation of nematode larval development; and regulation of brood size. Predicted to be part of aminoacyl-tRNA synthetase multienzyme complex. Predicted to be active in mitochondrion. Is expressed in several structures, including hypodermis; intestine; nervous system; pharynx; and reproductive system. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease recessive intermediate B and autosomal recessive nonsyndromic deafness 89. Orthologous to human KARS1 (lysyl-tRNA synthetase 1). [provided by Alliance of Genome Resources, Nov 2024]
