Aars2 Gene Summary [Rat]
Predicted to enable alanine-tRNA ligase activity; aminoacyl-tRNA deacylase activity; and peptide lactyltransferase (ATP-dependent) activity. Predicted to be involved in mitochondrial alanyl-tRNA aminoacylation and negative regulation of cGAS/STING signaling pathway. Predicted to be located in cytoplasm. Predicted to be active in mitochondrion. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 8 and progressive leukoencephalopathy with ovarian failure. Orthologous to human AARS2 (alanyl-tRNA synthetase 2, mitochondrial). [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 rat Aars2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
