Enables adenylate kinase activity. Contributes to phosphotransferase activity, phosphate group as acceptor. Involved in several processes, including nervous system development; nucleobase-containing small molecule metabolic process; and positive regulation of neuron maturation. Located in neuron projection; perinuclear region of cytoplasm; and sarcomere. Biomarker of middle cerebral artery infarction; myocardial infarction; and type 2 diabetes mellitus. Human ortholog(s) of this gene implicated in congenital nonspherocytic hemolytic anemia and hemolytic anemia. Orthologous to human AK1 (adenylate kinase 1).
