Distinct Patterns of Cleavage and Translocation of Cell Cycle Control Proteins in CD95-induced and p53-induced apoptosis

Park WS, Jung KC, Chung DH, Nam WD, Choi WJ, Bae Y

Apoptotic cell death induced by p53 occurs at a late G1 cell cycle checkpoint termed the restriction(R)point, and it has been proposed that p53-induced apoptosis causes upregulation of CD95. However,...
