This is a histone 4 peptide acetylated with lysine 8. In some studies, this histone modification is thought to predict the prognosis of resected non-small cell lung cancer. This peptide has also been shown to play a role in somatic hypermutation (SHM), because its modification may mediate the recruitment of error-prone DNA polymerases during the DNA repair phase of SHM.
