For example, proteases regulate the activation or inactivation of various proteins, such as enzymes, growth factors, and peptide hormones. Proteases have substrate specificity, and protease expression regulates the specific and regional activation or inactivation of several functional proteins %K Protease specificity %K Mass spectrometry %K Biotin-labeled peptides %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5418938/
