Summary: Enables leucine-tRNA ligase activity and pre-mRNA intronic binding activity. Involved in Group I intron splicing; leucyl-tRNA aminoacylation; and mitochondrial translation. Located in mitochondrion. Used to study Perrault syndrome and mitochondrial metabolism disease. Human ortholog(s) of this gene implicated in Perrault syndrome. Orthologous to human LARS2 (leucyl-tRNA synthetase 2, mitochondrial). [provided by Alliance of Genome Resources, Apr 2022]

What's a GeneRIF?

Self-protective responses to norvaline-induced stress in a leucyl-tRNA synthetase editing-deficient yeast strain has been reported.
Title: Self-protective responses to norvaline-induced stress in a leucyl-tRNA synthetase editing-deficient yeast strain.
Data show that the activity of the minimized bI4 intron was enhanced in vitro by the presence of the bI4 maturase or LeuRS.
Title: Leucyl-tRNA synthetase-dependent and -independent activation of a group I intron.
yeast mitochondria have evolved to tolerate lower levels of fidelity in protein synthesis or have developed alternate mechanisms to enhance discrimination of leucine from non-cognate amino acids that can be misactivated by leucyl-tRNA synthetase
Title: A viable amino acid editing activity in the leucyl-tRNA synthetase CP1-splicing domain is not required in the yeast mitochondria.
