Histone Phosphorylation in Epigenetic Regulation

    cover

    Kinases such as Aurora and ATM/ATR install histone phosphorylation; phosphatases reverse it. Marks like H3S10ph and γ-H2AX anchor transcription and repair complexes.

    Key Takeaways

    • H3S10/H3S28 linked to activation.

    • γ-H2AX marks DNA double-strand breaks.

    • Aurora B drives mitotic H3S10 phosphorylation.

    • Combines with acetylation and methylation in histone codes.T

    FAQ

    1. What is γ-H2AX?

    H2AX Ser139 phosphorylation recruiting DNA repair factors.

    2. How is it measured?

    Antibodies or LC-MS/MS with phosphopeptide enrichment.

    Conclusion

    Histone phosphorylation is a fast epigenetic switch integrated with other histone marks.
