Predicted to enable several functions, including DNA binding activity; gamma-tubulin binding activity; and purine ribonucleoside triphosphate binding activity. Acts upstream of or within lactation. Located in mitochondrion and myelin sheath. Is expressed in several structures, including alimentary system; brain; genitourinary system; integumental system; and sensory organ. Human ortholog(s) of this gene implicated in neuroblastoma; ovary epithelial cancer; and teratoma. Orthologous to human NME1 (NME/NM23 nucleoside diphosphate kinase 1).
