Predicted to enable phenylalanine-tRNA ligase activity and tRNA binding activity. Predicted to be involved in phenylalanyl-tRNA aminoacylation and tRNA processing. Located in mitochondrion. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 14 and hereditary spastic paraplegia 77. Orthologous to human FARS2 (phenylalanyl-tRNA synthetase 2, mitochondrial). [provided by Alliance of Genome Resources, Apr 2022]
