Chk2: Lysates

The Chk2 checkpoint kinase is an integral member of the signaling cascade that controls cell cycle checkpoints. In response to genotoxic insults Chk2 is phosphorylated by ATM or ATM-related kinases. Phosphorylation of Chk2 T68 promotes the formation of Chk2 oligomers. Oligomerization is a critical event in the activation of the Chk2 kinase a...
