H4K16ac contributes to chromatin compartment reorganization during mitotic and meiotic transitions [CUTnTAG]

GSE304211 Mus musculus Genome binding/occupancy profiling by high throughput sequencing 128 samples Submitted 2026/05/27 Platform GPL24247
Summary
Chromatin compartments reorganize dramatically during cell cycle transitions, shifting from a compartmentalized interphase to a condensed mitotic configuration in which large-scale compartment signals are attenuated. While histone modifications are linked to compartment identity, their contribution to compartment organization remains unclear. Using meiotic (mouse spermatogenesis) and mitotic (mouse neuronal progenitor cell, mNPC) models, we mapped histone landscapes alongside compartment dynamics. We found that histone H4 lysine 16 acetylation (H4K16ac) strongly tracked compartment reorganization, remaining enriched in A compartments during compartmentalization but redistributing upon chromatin compaction. In spermatogenesis, H4K16ac loss on the X chromosome coincided with condensation and H3K9me3 spreading. Machine learning highlighted H4K16ac as a stronger predictor of compartment transitions than H3K27ac. Acute degradation of MOF, the principal H4K16ac acetyltransferase, disrupted both the spatial distribution and global abundance of H4K16ac and progressively impaired compartmentalization in mNPCs. These results position H4K16ac as a histone modification selectively coupled to chromatin compartment transitions.
