摘要

Nm23 genes, which encode nucleoside diphos- phate kinases, have been implicated in suppressing tumor metastasis. The motility of human breast carcinoma cells can be suppressed by transfection with wild-type nm23-H1, but not by transfections with two nm23-H1 mutants, nm23-H1~S12OG and nm23-H1~P96S. Here we report that nm23-H1 can transfer a phosphate from its catalytic histidine to aspartate or glutamate residues on 43-kDa membrane proteins. One of the 43-kDa membrane proteins was not phosphorylated by either nm23-H1~P96S or nm23-H1~S120G, and another was phosphory- lated much more slowly by nm23-H1~P96S and by nm23-H1~S120G than by wild-type nm23-H1.
