    Summary
    Predicted to enable GTPase activator activity and catalytic activity, acting on a tRNA. Predicted to be involved in several processes, including cellular response to L-leucine; cellular response to leucine starvation; and tRNA aminoacylation for protein translation. Predicted to be located in several cellular components, including endoplasmic reticulum; lysosome; and nuclear body. Predicted to be part of aminoacyl-tRNA synthetase multienzyme complex. Human ortholog(s) of this gene implicated in infantile liver failure syndrome 1. Orthologous to human LARS1 (leucyl-tRNA synthetase 1). [provided by Alliance of Genome Resources, Dec 2024]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
