Predicted to enable nucleoside diphosphate kinase activity. Predicted to be involved in CTP biosynthetic process; GTP biosynthetic process; and UTP biosynthetic process. Predicted to act upstream of or within nucleotide metabolic process and phosphorylation. Located in mitochondrion. Is expressed in several structures, including gut; hemolymphoid system gland; nervous system; respiratory system; and sensory organ. Orthologous to human NME3 (NME/NM23 nucleoside diphosphate kinase 3). [provided by Alliance of Genome Resources, Apr 2022]
