Family: Chromo domain

lacks the SH3-like barrel first strand that can be complemented by bound peptide ligand; in shadow chromo domain the corresponding site is altered by insertion; similarity to the IL8-like fold

Lineage:

  1. Root: scop
  2. Class: All beta proteins [48724]
  3. Fold: SH3-like barrel [50036]
    barrel, partly opened; n*=4, S*=8; meander
    the last strand is interrupted by a turn of 3-10 helix
  4. Superfamily: Chromo domain-like [54160]
    SH3-like barrel is capped by a C-terminal helix

  5. Family: Chromo domain [54165]
    lacks the SH3-like barrel first strand that can be complemented by bound peptide ligand; in shadow chromo domain the corresponding site is altered by insertion; similarity to the IL8-like fold
