- * Histone H3 signatures *
- *************************
-
- 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].
-
- Caenorhabditis elegans chromosome III encodes two highly related proteins
- - known as F54C8.2 and F58A4.3 - whose C-terminal section is evolutionary
- related to the last 100 residues of H3 [3]. The function of these proteins is
- not yet known.
-
- In yeast chromosome XI, there is also a H3-like protein, YKL049c [4].
-
- 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.
-
- -Consensus pattern: K-A-P-R-K-Q-L
- -Sequences known to belong to this class detected by the pattern: ALL, except
- for the C.elegans and yeast H3-like proteins.
- -Other sequence(s) detected in SWISS-PROT: NONE.
-
- -Consensus pattern: P-F-x-R-L-V-[KRQ]-[DE]-[IV]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: NONE.

- -Last update: June 1994 / Patterns and text revised.
