These results suggest that ( 1 ) the differentiation inhibitory activity of I-factor /nm23 protein is not restricted to monocytic differentiation of M1 cells , ( 2 ) the inhibitory activity is exhibited without species specificity , and ( 3 ) the differentiation inhibitory activity of the nm23/NDP kinase protein is independent of its enzyme activity and requires the presence of N-terminal peptides .
