Gelatinase B functions as regulator and effector in leukocyte biology

Matrix metalloproteinases (MMPs) form a family of enzymes with major actions in the remodeling of extracellular matrix (ECM) components. Gelatinase B (MMP-9) is the most complex family member in terms of domain structure and regulation of its activity. Gelatinase B activity is under strict control at various levels: transcription of the gene by cytokines and cellular interactions; activation of the pro-enzyme by a cascade of enzymes comprising...
