Predicted to enable glutamine-tRNA ligase activity; protein kinase binding activity; and protein kinase inhibitor activity. Predicted to be involved in several processes, including glutaminyl-tRNA aminoacylation; negative regulation of nitrogen compound metabolic process; and negative regulation of signal transduction. Predicted to be located in cytoplasm. Predicted to be part of aminoacyl-tRNA synthetase multienzyme complex. Predicted to be active in cytosol. Biomarker of sciatic neuropathy. Orthologous to human QARS1 (glutaminyl-tRNA synthetase 1). [provided by Alliance of Genome Resources, Apr 2022]
