(A) Schematic representation of the experimental workflow in cultured hippocampal neurons.
(B and C) Chromatin immunoprecipitation (ChIP) was used to assess binding of (B) H2A.Z (n = 13–17/group) or (C) Anp32e (N = 8–10/group) in the first nucleosome downstream (+1 nucleosome) of the transcription start site (TSS) and in the coding region 30 min after KCl depolarization. H2A.Z binding is normalized to H3 and data are expressed as mean ± SEM. *p ≤ 0.05.
(D) Schematic representation of nucleosome salt fractionation.
(E) MNase fractionation and salt extraction of primary hippocampal neuronal nuclei were used to assess Anp32e binding to H2A.Z in distinct chromatin fractions.
