Mapping of histone-binding sites in histone replacement-completed spermatozoa
Abstract
While a majority of histones are replaced by protamines during spermatogenesis, a small amount is retained in mammalian spermatozoa. Here the authors develop a method to purify histones from replacement-completed sperm (HRCS), completely solubilize histones from cross-linked HRCS without MNase digestion, and map histone-binding sites in these cells.
