Histone Phosphorylation in Epigenetic Regulation

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.
