[Term] id: PR:000027563 name: histone H2A-alpha phosphorylated 1 def: "A histone H2A-alpha phosphorylated form in which the phosphorylation occurs within the [ST]Q motif at the C-terminus that constitutes a recognition sequence for kinases from the PI3/PI4-kinase family. Phosphorylated in response to DNA double-strand breaks generated by exogenous genotoxic agents and by stalled replication forks. Example: UniProtKB:P04909, Ser-129, MOD:00046."
