SCOP 1.75: Domain d1q3la_: 1q3l A:

Lineage for d1q3la_ (1q3l A:)

1. Root: SCOP 1.75

2. Class b: All beta proteins [48724] (174 folds)

3. Fold b.34: SH3-like barrel [50036] (21 superfamilies)
   barrel, partly opened; n*=4, S*=8; meander
   the last strand is interrupted by a turn of 3-10 helix

4. Superfamily b.34.13: Chromo domain-like [54160] (3 families)
   SH3-like barrel is capped by a C-terminal helix

5. Family b.34.13.2: Chromo domain [54165] (7 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

6. Protein Heterochromatin protein 1, HP1 [54166] (3 species)
   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] (3 PDB entries)
   Uniprot P05205 23-74

8. Domain d1q3la_: 1q3l A: [111652]
   complexed with histone H3 tail containing monomethyllysine 9 (Uniprot P16106 5-10), chain P
   complexed with mlz
