Chromosome missegregation and apoptosis in mice lacking the mitotic checkpoint protein Mad2.

abstract：:The pattern of histone modifications, called the histone code, influences transitions between chromatin states and the regulation of transcriptional activity. Four recent papers describe how plant homeodomain (PHD) finger proteins read part of this code. The PHD finger may promote both gene expression and repression t...
