Single stranded-DNA detection: the role of Wip1 in ATR-dependent pathway
Single-stranded DNA (ssDNA) areas arise in cells as a result of exposure to stress agents - like UVC - or during repair of DNA double-strand breaks. ATR(ataxia telangiectasia mutated and Rad3-related) is responsible for detecting ssDNA. Recently, it has been shown that one of the most important components of cellular response to the damage is Wip1 phosphatase, which inactivates main elements of DNA damage response (DDR) pathways. We developed a mathematical model of ATR detector system, connected...
