OsOTUB1 displayed cleavage activity for K48- and K63-linked ubiquitin tetramers. Cleavage activity towards K48- and K63-linked ubiquitin tetramers (Tetra-ub) was analysed using OTUB1, His-OsOTUB1.1 or OsOTUB1.2. The inputs (Ub4) and their cleavage products (trimers (Ub3), dimers (Ub2) and monomers (Ub1)) are labelled on the left. The products were visualised via western blotting using an anti-ubiquitin antibody.
