The nm23 gene, a potential suppressor of metastasis, was originally identified by differential hybridization between two murine melanoma sub-lines, one with a high and the second with a low metastatic capacity. Highly metastatic sublines exhibit much lower levels of nm23 than less metastatic cells. Based on sequence analysis, nm23 appears highly related to nucleotide diphosphate kinases (NDP). In humans, NDP kinases A and B are identical to two isotypes of human nm23 homologs, namely nm23-H1 and -H2, respectively. nm23-H2 is identical in sequence to PuF, a transcription factor that binds to nucleasehypersensitive elements at positions 142 to 115 of the human c-Myc promotor.Synonyms: GAAD, Granzyme A-activated DNase, NDPKA, NM23, NME1, Nucleoside diphosphate kinase A, nm23-H1
