Predicted to enable several functions, including bis(5'-nucleosyl)-tetraphosphatase (asymmetrical) activity; glycine-tRNA ligase activity; and identical protein binding activity. Predicted to be involved in diadenosine tetraphosphate biosynthetic process and tRNA aminoacylation for protein translation. Predicted to act upstream of or within glycyl-tRNA aminoacylation. Predicted to be located in several cellular components, including axon; extracellular exosome; and secretory granule. Human ortholog(s) of this gene implicated in Charcot-Marie-Tooth disease type 2D and distal hereditary motor neuronopathy type 5A. Orthologous to human GARS1 (glycyl-tRNA synthetase 1).
