| PDB codes | Protein functions | LRR classes | InterPro | Swiss-Prot | Pfam | SMART | LRRML |
| 2A0Z | Immune System | T | 18 | 22 | 7 | 20 | 25 |
| 1G9U | Toxin | S | 7 | 15 | 1 | 0 | 15 |
| 2FT3 | Structural Protein | T+S | 8 | 8 | 5 | 9 | 12 |
| 1K5D | Signaling Protein | RI | 2 | 8 | 0 | 0 | 11 |
| 1GWB | Glycoprotein | SDS22 | 6 | 6 | 4 | 7 | 8 |
| 2P1M | Signaling Protein | CC | 2 | 16 | 0 | 6 | 18 |
