Quantifying Symmetrically Methylated H4R3 on the Kaposi's Sarcoma-associated Herpesvirus (KSHV) Genome by ChIP-Seq

Post-translational modifications to histone tails contribute to the three-dimensional structure of chromatin and play an important role in detegrmining the relative expression of nearby genes. One such modification is symmetric di-methylation of arginine residues, which may exhibit different effects on gene expression including blocking the binding of transcriptional activators, or recruiting repressive effector molecules. Recent ChIP-Seq studies have demonstrated the importance of cross-talk between different histone modifications in gene regulation. Thus, to acquire a comprehensive understanding of the combined efforts of these epigenetic marks, ChIP-Seq must be utilized for identifying specific enrichment on the chromatin. Tumorigenic herpesvirus KSHV, employs epigenetic mechanisms for gene regulation, and by evaluating relative abundance of multiple histone modifications in a thorough, unbiased way, using ChIP-Seq, we can get a superior insight concerning the complex mechanisms of viral replication and pathogenesis.
