Summary: Enables Ser-tRNA(Ala) hydrolase 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 trichothiodystrophy. Orthologous to human AARS1 (alanyl-tRNA synthetase 1). [provided by Alliance of Genome Resources, Nov 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.
