Describe how H3Lys9me heterochromatin is formed ~~> H3Lys9me heterochromatin formation: Lys9 deacetylated by HDAC. Suvar39 then methylates lys9. Methylated lys9 is recognised by HP1 and then HP1 binds. HP1 has chromodomain - chromodomains often recognise and bind to methylated lys residues. Chromodomain on HP1 is specific for H3Lys9me (with di or tri methylated lys 9). Binding of HP1 is thought to compact nucleosome arrays as HP1s join together. What is gene expression? ~~> ...
