tokens: Furthermore , compared with wild-type Id3 , an Id3 Asp5 mutant ( mimicking phosphorylation ) is unable to promote cell cycle S phase entry in transfected fibroblasts , whereas an Id3 Ala5 mutant ( ablating phosphorylation ) displays an activity significantly greater than that of wild-type Id3 protein .
