Predicted to enable adenylate kinase activity. Predicted to contribute to nucleobase-containing compound kinase activity. Predicted to be involved in ATP metabolic process and purine nucleotide metabolic process. Predicted to act upstream of or within phosphorylation. Located in sperm mitochondrial sheath. Is expressed in several structures, including alimentary system; brain; genitourinary system; musculoskeletal system; and sensory organ. Human ortholog(s) of this gene implicated in reticular dysgenesis. Orthologous to human AK2 (adenylate kinase 2). [provided by Alliance of Genome Resources, Apr 2022]
