Abstract

Legumain (asparaginyl endopeptidase) is the only protease with a preference for cleavage after asparagine residues. Increased legumain activity is a hallmark of inflammation, neurodegenerative diseases, and cancer, and legumain inhibitors have exhibited therapeutic effects in mouse models of these pathologies. Improved knowledge of its substrates and cellular functions is a requisite to further validation of legumain as a drug target. We, therefore, aimed to investigate the effects of legumain inhibition in macrophages using an unbiased and systematic approach. By shotgun proteomics, we identified 16 »094 unique peptides in RAW264.7 cells. Among these, 326 unique peptides were upregulated in..
