Histones, fundamental nuclear proteins, form the nucleosome structure of eukaryotic chromosomes. Each nucleosome comprises around 146 base pairs of DNA wrapped around a histone octamer, consisting of pairs of the four core histones (H2A, H2B, H3, and H4). Further compaction occurs via interaction of linker histone H1 with DNA between nucleosomes, creating higher-order chromatin structures. This gene, lacking introns, encodes a histone H4 family member. Its transcripts lack polyA tails, instead featuring a palindromic termination element.
