Histone H2B.8 compacts flowering plant sperm through chromatin phase separation

ABSTRACT: We characterised a sperm-expressed histone variant, H2B.8 in Arabidopsis by performing ChIP-seq, RNA-seq, and Hi-C. The data show that H2B.8 is exclusively deposited to unexpressed euchromatin and that gene expression is not significantly affected either by h2b.8 mutation in sperm or overexpression in soma. The deposition of H2B.8increases the contact probability of short range intrachromosomal interactions and contacts between pericentomeric regions and chromosome arms of different chromosomes.

Molecular basis of RanGTP-activated release of Histones H2A-H2B from Importin-9

Project description:Imp9 is the primary importin for shuttling H2A-H2B from the cytoplasm to the nucleus. It employs an unusual mechanism where the binding of RanGTP is insufficient to release H2A-H2B. The resulting stable RanGTP•Imp9•H2A-H2B complex gains nucleosome assembly activity with H2A-H2B able to be deposited into an assembling nucleosome in vitro. Using hydrogen-deuterium exchange coupled with mass spectrometry (HDX), we show that Imp9 stabilizes H2A-H2B beyond the direct binding site, like other histone chaperones. HDX also shows that binding of RanGTP releases H2A-H2B contacts at Imp9 HEAT repeats 4-5, but not 18-19. DNA- and histone-binding surfaces of H2A-H2B are exposed in the ternary complex, facilitating nucleosome assembly. We also reveal that RanGTP has a weaker affinity for Imp9 when H2A-H2B is bound. Imp9 thus provides a connection between the nuclear import of H2A-H2B and its deposition into chromatin.
