Lineage for Family a.47.4.1: CAPPD, an extracellular domain of amyloid beta A4 protein

1. Root: SCOP 1.71

2. Class a: All alpha proteins [46456] (226 folds)

3. Fold a.47: STAT-like [47654] (4 superfamilies) 4 long helices; bundle, left-handed twist (coiled coil); right-handed superhelix

4. Superfamily a.47.4: CAPPD, an extracellular domain of amyloid beta A4 protein [109843] (1 family) the first three helices are longer than the fourth one and, taken separately, adopt a Spectrin repeat-like fold (scop_cf 46965)
