Histone Phosphorylation Assay

Introduction

Histone phosphorylation is a post-translational modification that involves the addition of a phosphate group to a histone protein. This process can occur at specific amino acid residues on the histone and is conserved among eukaryotes. Phosphorylation of histone H3 at serine 10 and serine 28 has been shown to be correlated with gene activation and cell growth.

Importance in Gene Expression

Histone phosphorylation plays a key role in regulating gene expression and has been implicated in various biological processes such as DNA repair, cell cycle progression, and the immune response. Dysregulation of histone phosphorylation has been linked to various diseases, including cancer and neurological disorders.

Modulation by Protein Kinases

Phosphorylation of histones is modulated by protein kinases, enzymes that transfer a phosphate group from ATP to specific amino acid residues on the protein substrate. Measuring changes in histone phosphorylation levels can provide insight into the underlying biological and pathological processes occurring in a cell or tissue, and can also be useful for protein kinase-targeted drug development.
