| catalytic Activity | CATALYTIC ACTIVITY: Reaction=Similar to cathepsin L, but with much less activity on Z-Phe-Arg-|-NHMec, and more activity on the Z-Val-Val-Arg-|-Xaa compound.; EC=3.4.22.27; |
| DNA Binding | |
| EC Number | 3.4.22.27 |
| Enzyme Function | FUNCTION: Thiol protease. Key protease responsible for the removal of the invariant chain from MHC class II molecules and MHC class II antigen presentation. The bond-specificity of this proteinase is in part similar to the specificities of cathepsin L. {ECO:0000250|UniProtKB:P25774}. |
