A disintegrin and metalloproteinase (ADAM) family proteins constitute a major class of membrane-anchored multidomain proteinases that are responsible for the shedding of cell-surface protein ectodomains, including the latent forms of growth factors, cytokines, receptors and other molecules. Snake venom metalloproteinases (SVMPs) are major components in most viper venoms. SVMPs are primarily res...
Interactions between connective tissue substrates and proteinases localized to the surface of cancer cells are implicated in cancer invasion. In this report we have compared the enrichment of collagen and gelatin degrading activities and cysteine proteinase(s) in well-characterized (enzyme markers and electron microscopy) subcellular membrane fractions isolated from human small cell lung cancer...
Porphyromonas gingivalis is a major pathogen associated with chronic periodontitis. The organism's cell-surface cysteine proteinases, the Arg-specific proteinases (RgpA, RgpB) and the Lys-specific proteinase (Kgp), which are known as gingipains have been implicated as major virulence factors. All three gingipain precursors contain a propeptide of around 200 amino acids in length that is removed...
Type I collagen fibers account for 90% of the organic matrix of bone. The degradation of this collagen is a major event during bone resorption, but its mechanism is unknown. A series of data obtained in biological models strongly suggests that the recently discovered cysteine proteinase cathepsin K plays a key role in bone resorption. Little is known, however, about the actual action of catheps...
