Phosphorylated histone h2ax
WebSep 14, 2012 · Importantly, H2AX was efficiently phosphorylated in heterochromatin during DNA replication, when heterochromatin organization is more relaxed . Thus differences between euchromatin and heterochromatin in γH2AX foci induction by X-rays might be related to differences in condensation state rather than heterochromatin being refractory … WebJul 1, 2024 · Histone H2AX phosphorylated at serine 139 (γ-H2AX) is a hallmark of DNA damage, signaling the presence of DNA double-strand breaks and global replication stress in mammalian cells. While γ-H2AX can be visualized with antibodies in fixed cells, its detection in living cells was so far not possible.
