Histone H4
SMART accession number:SM00417
Description: -
Interpro abstract (IPR001951):

Histone H4 is one of the five histones, along with H1/H5, H2A, H2B and H3. Two copies of each of the H2A, H2B, H3, and H4 histones ensemble to form the core of the nucleosome [ (PUBMED:16472024) ]. The nucleosome forms octameric structure that wraps DNA in a left-handed manner. H3 is a highly conserved protein of 135 amino acid residues [ (PUBMED:8121801) (PUBMED:2041803) ]. Histones can undergo several different types of post-translational modifications that affect transcription, DNA repair, DNA replication and chromosomal stability. The sequence of histone H4 has remained almost invariant in more then 2 billion years of evolution [ (PUBMED:8121801) (PUBMED:6808351) (PUBMED:3340182) ].
