Abstract

In a recent issue of Molecular Cell, Shiotani and Zou (2009) elucidate the biochemical mechanism underlying sequential ATM and ATR activation at DNA double-strand breaks, demonstrating that resection transforms ATM substrates into ATR substrates.

摘要

在最近一期的《分子细胞》杂志上,盐谷和邹(2009年)阐明了DNA双链断裂处ATM和ATR顺序激活背后的生化机制,证明了切除作用将ATM底物转化为ATR底物。
