Aars Gene Summary [Mouse]
Enables Ser-tRNA(Ala) deacylase activity and alanine-tRNA ligase activity. Involved in alanyl-tRNA aminoacylation; regulation of cytoplasmic translational fidelity; and tRNA modification. Acts upstream of or within cerebellar Purkinje cell layer development; negative regulation of neuron apoptotic process; and neuromuscular process controlling balance. Predicted to be located in cytosol. Predicted to be active in mitochondrion and nucleus. Is expressed in several structures, including adrenal gland; alimentary system; nervous system; respiratory system; and urinary system. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease axonal type 2N; developmental and epileptic encephalopathy 29; leukodystrophy; and nonphotosensitive trichothiodystrophy 8. Orthologous to human AARS1 (alanyl-tRNA synthetase 1). [provided by Alliance of Genome Resources, Apr 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 Aars often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
