These data provide further evidence that CDK9 phosphorylates H1.4-S187, and that the level of pS187-H1.4 at genes is directly related to the extent of co-enrichment of CDK9.|that enrichment of pS187-H1.4 at genes is positively related to their transcription. |

we showed previously that phosphorylation of S27 in human histone H1.4 (H1.4S27-P), prevents binding of heterochromatin protein 1 (HP1) family members (officially known as chromobox protein homologs) to the neighboring dimethylated K26. Here, we present the first functional characterization of H1.4S27-P in vivo and in vitro. We show that H1.4S27 phosphorylation is cell-cycle-regulated and its levels peak on metaphase chromosomes. We identify further Aurora B as the kinase phosphorylating H1.4S27. |
