PROSITE documentation PDOC00287Histone H3 signatures
Description
Histone H3 is one of the four histones, along with H2A, H2B and H4, which forms the eukaryotic nucleosome core. It is a highly conserved protein of 135 amino acid residues [1,2,E1].
The following proteins have been found to contain a C-terminal H3-like domain:
- Mammalian centromeric protein CENP-A [3]. Could act as a core histone necessary for the assembly of centromeres.
- Yeast chromatin-associated protein CSE4 [4].
- Caenorhabditis elegans chromosome III encodes two highly related proteins (F54C8.2 and F58A4.3) whose C-terminal section is evolutionary related to the last 100 residues of H3. The function of these proteins is not yet known.
We developed two signature patterns, The first one corresponds to a perfectly conserved heptapeptide in the N-terminal part of H3. The second one is derived from a conserved region in the central section of H3.
