WebApr 15, 2000 · Chk2 is of particular interest, because it is phosphorylated in an ATM-dependent manner upon treatment with ionising radiation [7]. A new study using Chk2 … WebAug 23, 2024 · Chk1 and Chk2 phosphorylate and stabilize p53, which acts as a transcription factor to induce genes involved in cell cycle arrest and apoptosis. Since the discovery of the p53 ortholog ( Ollmann et al., 2000 ; Brodsky et al., 2000 ), a key regulator of DDR, Drosophila has served as a model system for studying DDR ( Song, 2005 ). WebOur results indicate that MNK/Chk2-dependent modification of Drosophila p53 activates a global transcriptional response to DNA damage that induces error-prone DNA repair as well as intrinsic and extrinsic apoptosis pathways.
