Scientists have verified the presence of a protein modification that is a unique mark in human cell nucleus. This protein modification, Histone H4 lysine 20 acetylation (H4K20ac), was only discovered in plant cells and its existence in mammalian cells has been indirectly proven. Their study suggests that H4K20ac is associated with gene repression. This new discovery of H4K20ac may lead to further clarification of the mechanisms in disease progression.
