Lineage for Family b.34.13.2: Chromo domain

  1. Root: SCOP 1.69
  2. 450777Class b: All beta proteins [48724] (144 folds)
  3. 461193Fold b.34: SH3-like barrel [50036] (15 superfamilies)
    barrel, partly opened; n*=4, S*=8; meander
    the last strand is interrupted by a turn of 3-10 helix
  4. 461839Superfamily b.34.13: Chromo domain-like [54160] (2 families) (S)
    SH3-like barrel is capped by a C-terminal helix
  5. 461859Family b.34.13.2: Chromo domain [54165] (3 proteins)
    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

Proteins:

  1. 461860Heterochromatin protein 1, HP1 [54166] (3 species)
    duplication: consists of two homologous domains, N-terminal chromo domain and C-terminal chromo shadow domain
