Description

This pathway is modeled after Figure 1 in the article " ATR signalling: more than meeting at the fork" (See Bibliography). This pathway details the ATR signaling which commences when there is a gap in the single strand DNA. It details the usage of several independent checkpoint proteins which then cause TOPBP1 dependent activation of the phosphorylation and kinase of a large number of substrates including CHK1 to commence regulation of cellular response to DNA damage and replication stress.
