SCOP 1.69: Protein: Polycomb protein, Pc

Lineage for Protein: Polycomb protein, Pc

Root: SCOP 1.69
Class b: All beta proteins [48724] (144 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] (2 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
