Nars2 Gene Summary [Mouse]
Predicted to enable asparagine-tRNA ligase activity. Predicted to be involved in asparaginyl-tRNA aminoacylation. Located in mitochondrion. Is expressed in embryo; extraembryonic component; and primitive endoderm. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 94 and combined oxidative phosphorylation deficiency 24. Orthologous to human NARS2 (asparaginyl-tRNA synthetase 2, mitochondrial). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in mouse Nars2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
