There are five types of histones that have been identified: H1 (or H5), H2A, H2B, H3 and H4, the core histones are H2A, H2B, H3, and H4, and the linker histones are H1 and H5. H1 as well as its homologous protein H5 are involved in higher-order chromatin structures. The other four types of histones form … Webb29 juli 2024 · SWI1 promotes histone H4 acetylation by stabilizing the expression of NuA4. Loss of SWI1 leads to the instability of chromatin modification-related protein vid21, a regulatory subunit of NuA4, leading to a reduction in histone H4 acetylation ( 79 ).
