Lineage for Species: Human (Homo sapiens), calpain 9 [TaxId: 9606]

1. Root: SCOPe 2.08

2. Class d: Alpha and beta proteins (a+b) [53931] (396 folds)

3. Fold d.3: Cysteine proteinases [54000] (1 superfamily) consists of one alpha-helix and 4 strands of antiparallel beta-sheet and contains the catalytic triad Cys-His-Asn

4. Superfamily d.3.1: Cysteine proteinases [54001] (24 families) the constitute families differ by insertion into and circular permutation of the common catalytic core made of one alpha-helix and 3-strands of beta-sheet

5. Family d.3.1.3: Calpain large subunit, catalytic domain (domain II) [54040] (1 protein) automatically mapped to Pfam PF00648

6. Protein Calpain large subunit, catalytic domain (domain II) [54041] (6 species) includes the N-terminal 'sequence' domain I

7. Species Human (Homo sapiens), calpain 9 [TaxId:9606] [142850] (1 PDB entry) Uniprot O14815 28-337
