Description

UbiQ-262 is a potent, irreversible and specific activity-based probe for ISG15 proteases. It is prepared by total chemical synthesis and based on the proximal part of mouse ISG15. To improve stability, Cys77 and Cys144 are replaced by Ser. It contains a C-terminal vinyl pentynyl sulfone (VPS) electrophile which allows for post-labeling modification of cross-linked [UbiQ-237]::[ISG15 protease] complexes by using click chemistry with for example biotin-azide.
