FAMILY
  • histone H3 family
  • CATEGORY structural protein , DNA associated , transcription factor
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus,nucleoplasm
    intracellular,nucleus,chromatin/chromosome,nucleosome
    basic FUNCTION
  • replacement histone protein, independent from the cell cycle
  • playing a role in the compaction of DNA into nucleosomes
  • H3F3A, H3F3B has multiple functions in distinct genomic locations that are not always correlated with an “active” chromatin state
  • H3F3A, H3F3B are not required for active transcription but instead may be necessary for establishing a chromatin landscape allowing for proper gene expression upon differentiation
  • H3F3A, H3F3B are a crucial maternal factor for oocyte reprogramming, providing a practical model to directly dissect the oocyte for its reprogramming capacity
  • CELLULAR PROCESS nucleotide, chromatin organization, remodeling
    nucleotide, transcription, regulation
