WebMay 10, 2024 · H3.3 promotes active histone modifications at FLC and its homologs Previous RNA-seq results in h3.3kd have shown that only a small portion of H3.3-enriched genes were misregulated, suggesting that the loss of H3.3 per se might not be enough to alter transcription activity ( Wollmann et al., 2024 ). WebHistone variants are proteins that substitute for the core canonical histones ( H3, H4, H2A, H2B) in nucleosomes in eukaryotes and often confer specific structural and functional features. The term might also include a set of linker histone (H1) variants, which lack a distinct canonical isoform.
