Protein: Heterochromatin protein 1, HP1 from Fruit fly (Drosophila melanogaster) [TaxId: 7227]

SQ P05205 23-74

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
    link to SUPERFAMILY database - Superfamily
  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
  6. Protein: Heterochromatin protein 1, HP1 [54166]
    duplication: consists of two homologous domains, N-terminal chromo domain and C-terminal chromo shadow domain
  7. Species: Fruit fly (Drosophila melanogaster) [TaxId: 7227] [75343]
    SQ P05205 23-74
