| Class b: All beta proteins [48724] (149 folds) |
| Fold 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 |
Superfamily b.34.13: Chromo domain-like [54160] (3 families) ![]() SH3-like barrel is capped by a C-terminal helix |
| Family 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 |
| Protein Heterochromatin protein 1, HP1 [54166] (3 species) duplication: consists of two homologous domains, N-terminal chromo domain and C-terminal chromo shadow domain |
| Species Fruit fly (Drosophila melanogaster) [TaxId:7227] [75343] (3 PDB entries) |
| Domain d1q3la_: 1q3l A: [111652] complexed with histone H3 tail containing monomethyllysine 9 (SQ P16106 5-10), chain P complexed with mlz |
PDB Entry: 1q3l (more details), 1.64 Å
