Predicted to enable leucine-tRNA ligase activity. Predicted to be involved in leucyl-tRNA aminoacylation and mitochondrial translation. Predicted to be active in mitochondrion. Is expressed in several structures, including adult head; anal pad primordium; embryonic anal pad; embryonic/larval midgut primordium; and gut section. Human ortholog(s) of this gene implicated in Perrault syndrome. Orthologous to human LARS2 (leucyl-tRNA synthetase 2, mitochondrial).
