Dephosphorylation and polyubiquitination of the histone variant H2AX coordinately terminate DNA damage signaling in Arabidopsis
{{output}}
Both activation and termination of DNA damage response (DDR) are essential to maintain genome stability. It is well-known that the histone variant H2AX is rapidly phosphorylated to activate DDR in eukaryotes. But how H2AX signaling is terminated remains poorly... ...
