SCOPe 2.01: Domain d2i5yl1: 2i5y L:1-107

Lineage for d2i5yl1 (2i5y L:1-107)

1. Root: SCOPe 2.01

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

3. Fold b.1: Immunoglobulin-like beta-sandwich [48725] (28 superfamilies)
   sandwich; 7 strands in 2 sheets; greek-key
   some members of the fold have additional strands

4. Superfamily b.1.1: Immunoglobulin [48726] (5 families)

5. Family b.1.1.1: V set domains (antibody variable domain-like) [48727] (33 proteins)

6. Protein Immunoglobulin light chain kappa variable domain, VL-kappa [88519] (16 species)
   VL-kappa domains of human and mouse antibodies are clustered by the sequence similarity within the germline encoded segment and then by the size of the complementarity determining regions CDR1 and CDR2, so the clusters may correspond to putative germline families in the species genomes; VL-kappa domains with artificial or grafted exogenous CDRs are listed as engineered species

7. Species Human (Homo sapiens), cluster 3.2 [TaxId:9606] [88523] (35 PDB entries)

8. Domain d2i5yl1: 2i5y L:1-107 [137074]
   Other proteins in same PDB: d2i5yg_, d2i5yh1, d2i5yh2, d2i5yl2, d2i5ym1, d2i5yp_, d2i5yq2, d2i5yr1, d2i5yr2, d2i5ys1
   automatically matched to d1g9ml1
