Abstracts for oral presentations are invited for research on proteases in their molecular, cellular and organismic context. Methodological advances for studying aspects of the complex protease web as well as their interaction with substrates, activators and inhibitors are similarly highly sought after. When preparing your abstract, please follow the guidelines given under “Registration & Abstract Submission”.
