Hars Gene Summary [Mouse]
Predicted to enable several functions, including ATP binding activity; histidine-tRNA ligase activity; and protein homodimerization activity. Predicted to be involved in histidyl-tRNA aminoacylation and mitochondrial translation. Predicted to be located in cytoplasm. Predicted to be active in cytosol and mitochondrion. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease, axonal type 2W and Usher syndrome type 3B. Orthologous to human HARS1 (histidyl-tRNA synthetase 1).

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 Hars often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
