General description
A novel cysteine protease inhibitor that specifically and efficiently inhibits processing of the p-Prl signal peptide (IC50 = ~ 50 nM) without affecting the activities of signal peptidases and other proteases such as lysosomal cathepsins and proteasomes.
A novel cysteine protease inhibitor that specifically and efficiently inhibits processing of the p-Prl signal peptide (IC50 ~50 nM) without affecting the activities of signal peptidases and other proteases such as lysosomal cathepsins and proteasomes. (Z-LL)2 ketone does not cause any modification of the proteasomal active site even at 100 µM levels; hence it does not block the action of the multicatalytic proteasome complex.

Epithin/PRSS14, a type II transmembrane serine protease, is an emerging target of cancer therapy because of its critical roles in tumor progression and metastasis. In many circumstances, the protease, through its ectodomain shedding, exists as a soluble form and performs
