Abstract
p21-activated kinase 2 (PAK2) is proteolytically cleaved during apoptosis through the action of DEVD-sensitive caspase(s). This cleavage event causes PAK2 activation, and PAK2 activity is implicated in regulation of the biochemistry and morphology of the apoptotic cell. PAK2 is just one example of a number of identified caspase targets that are protein kinases involved in regulating various aspects of cell function. We hypothesize that this may reflect their important role in regulating the controlled and orderly demise of the dying cell.
