text_1: Replacement of histone H2A with H2A.Z accelerates gene activation in yeasts by destabilizing +1 nucleosomes.
text_2: We report here that H3.3 nucleosomes isolated from vertebrates, regardless of whether they are partnered with H2A or H2A.Z, are unusually sensitive to salt-dependent disruption, losing H2A/H2B or H2A.Z/H2B dimers.
