gammaH2Ax for my own sake memory!
PTM for Histone;
1. acetylation (Lys)
2. ubiquitination (Lys)
3. phosphorylation (Ser)
H2Ax when phosphorylate --> gammaH2Ax!
nucleosome = histone (H2A,H2B,H3,H4) + 147 bp DNA wrapping around 8 octa-histone and being locked with H1 (shown in my drawing)
For H2A subdivided to 3;
H2A1-H2A2 (balance from the other two)
H2Ax (2-25%)
H2Az (10%)
