Description
Linker histone H1 is a protein component of chromatin and has been linked to chromatin compaction and global gene silencing.It has been sugegsted that H1 plays a significant role, regulating a relatively small number of genes. Here we show that H1.2- a variant of H1 subtype is recruited to chromatin region and is dependent on EZH2-mediated H3K27me3. Therefore a Gene expression array analysis was carried out with H1.2 as well as EZH2 knockout MCF7 cells to confirm the interlationship of H1.2 and EZH2 activity.
