During S-phase, the cell continuously scrutinizes its genome for abnormalities. Detection of DNA damage induces activation of three canonical S-phase "checkpoint pathways" that delay or arrest further cell cycle progression: 1. The Replication Checkpoint detects stalled replication forks by integrating signals from RPA, ATR Interacting Protein (ATRIP), and RAD17. Upon activation, the replication checkpoint upregul… WebCCNB2 levels gradually increase during S and G2 phase and peak at mitosis. 29,30 It was reported that ER-positive patients who have high expression of CCNA2 or CCNB2 have inferior survival. 31,32 KIF4A, KIF20A and KIF23 are all mitotic kinesins and have a highly conserved motor domain involving ATP-binding and microtubule-binding sequences. 33 ... research methods psychology a level edexcel
