Cathepsin B is a cysteine protease commonly overexpressed in metastisizing cancer cells.
An intracellular (lysosomal) enzyme in peptidase family C1 (papain family), Cathepsin B will hydrolyze proteins with broad specificity for peptide bonds.
Preferentially cleaves -Arg-Arg bonds in small molecule substrates (thus differing from cathepsin L).
In addition to being an endopeptidase, shows peptidyl-dipeptidase activity, liberating C-terminal dipeptides.
Applications:Suitable for use in ELISA and Western Blot.
