WebEach nucleosome is made of two identical subunits, each of which contains four histones: H2A, H2B, H3, and H4. Meanwhile, the H1 protein acts as the linker histone to stabilize internucleosomal DNA and does not form part of the nucleosome itself. WebJul 14, 2024 · Histone H2A.B lacks the acidic patch and leads to decreased nucleosome stability. By contrast, H2A.Z contains an extended acidic patch that contributes to increased nucleosome stability in...
