nucleoside diphosphate kinase A. Major role in the synthesis of nucleoside triphosphates other than ATP. Holoenzyme is a hexamer of the A and B subunits. Mutations have been identified in aggressive neuroblastomas. Two transcript variants encoding different isoforms have been described. Note: This description may include information from UniProtKB.
