Histone H1 is one of the five main histone protein families which are components of chromatin in eukaryotic cells. Though highly conserved, it is nevertheless the most variable histone in sequence across species. See more Metazoan H1 proteins feature a central globular "winged helix" domain and long C- and short N-terminal tails. H1 is involved with the packing of the "beads on a string" sub-structures into a high order structure, whose details have … See more Unlike the other histones, H1 does not make up the nucleosome "bead". Instead, it sits on top of the structure, keeping in place the DNA that has wrapped around the nucleosome. H1 is present in half the amount of the other four histones, which contribute two … See more Like other histones, the histone H1 family is extensively post-translationally modified (PTMs). This includes serine and threonine phosphorylation, lysine acetylation, lysine methylation and ubiquitination. These PTMs serve a variety of functions but are … See more While most histone H1 in the nucleus is bound to chromatin, H1 molecules shuttle between chromatin regions at a fairly high rate. It is difficult to … See more The H1 family in animals includes multiple H1 isoforms that can be expressed in different or overlapping tissues and developmental stages within a single organism. The reason for these multiple isoforms remains unclear, but both their evolutionary … See more • Nucleosome • Histone • Chromatin • Linker histone H1 variants • Other histone proteins involved in chromatin: See more
