| CHARACTERIZATION | A new ribosome-inactivating protein (RIP), the N-terminal amino acid sequence of sechiumin is very similar to that of trichosanthin. |

| SOURCE TISSUE | |
| SPECIFICITY | |
| INHIBITORS | Sechiumin has a highly specific RNA N-glycosidase activity towards 28S rRNA, as does the A-chain of abrin. It suggests that sechiumin is one of the type-I ribosome-inactivating proteins. |
