Phosphoproteomics of ATR Signaling in Prophase I of Mouse Meiosis


ABSTRACT: Here we used phosphoproteomics to define meiosis-specific ATR signaling events during prophase I in mice following chemical and genetic ablation of ATR signaling. Quantitative analysis of phosphoproteomes obtained after tissue-specific genetic ablation of the ATR activating 9-1-1 complex or treatment with ATR inhibitor revealed over 49,800 phosphorylation sites from testes samples, of which 401 phosphorylation sites were found to be dependent on both the 9-1-1 complex and ATR kinase.
