- * Histone H4 signature *
- ************************
-
- Histone H4 is one of the four histones, along with H2A, H2B and H3, which
- forms the eukaryotic nucleosome core. Along with H3, it plays a central role
- in nucleosome formation. The sequence of histone H4 has remained almost
- invariant in more then 2 billion years of evolution [1]. The region we use as
- a signature pattern is a pentapeptide found in positions 14 to 18 of all H4
- sequences. It contains a lysine residue which is often acetylated [2] and a
- histidine residue which is implicated in DNA-binding [3].
-
- -Consensus pattern: G-A-K-R-H
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.
