A characteristic of lysosomal cysteine proteinases is given by their kinetic constants with specific substrates, their sequence homology, and their reactivity with monospecific polyclonal antibodies.

Journal of Histochemistry & Cytochemistry, 1981
Our interest in proteolytic enzymes derives from our work on the pathogenesis of multiple sclerosis (MS). In this disease of the central nervous system the myelin sheaths enveloping the axons disintegrate, usually in a patchy manner beginning around small veins or near the ventricles, resulting in lesions or “plaques.” The cause of MS is still unknown.

The primary agents responsible for cartilage and bone destruction in joint diseases are active proteinases degrading collagen and proteoglycan. All four main classes of proteolytic enzymes are involved in either the normal turnover of connective tissue or its pathological destruction.

Collagenolytic proteinases in keratoconus
American Journal of Ophthalmology, 2006To study the proteolytic phenomena contributing to the pathogenesis of keratoconus, corneal enzymes with potential to cleave fibrillar collagen were studied.Immunohistochemical labeling was undertaken of conventional and novel mammalian collagenases (MMP-1, -2, -8, -13, and -14) of the matrix metalloproteinase (MMP) family and other collagenolytic ...

Proteinase Inhibitors and Proteinases of Human Semen
1974During the First International Research Conference on Proteinase Inhibitors, a survey was presented concerning the proteinases of spermatozoa and seminal plasma as was known until that time [1, 2]. In summary, a proteinase from rabbit spermatozoa was purified and characterized, and shown to differ from other known pro-teolytic enzymes. It was given the

Microglial cells may be seen as a relay station between the periphery and central nervous system (CNS) – they are tasked with modulating signals from the periphery to protect the CNS from potential harm. As such, microglial cells are known as the sentinels of the brain.

Substrate recognition by proteinases
Faraday Discussions, 1992The molecular recognition of limited proteolytic site substrates by serine proteinases has been compared and contrasted to the recognition of serine proteinase inhibitors, utilising the coordinate sets contained in the Brookhaven Protein Databank. Most families of these inhibitors are known to possess a structurally conserved recognition motif at their

Proteinase 3. A neutrophil proteinase with activity on platelets.
The Journal of Immunology, 1994Abstract Purified proteinase 3 (PR3) devoid of any elastase (HLE) and cathepsin G (Cat.G) contaminants, was prepared from azurophilic granules of human polymorphonuclear neutrophils by using a novel procedure. Although unable to induce platelet activation (up to 25 micrograms/ml) by itself, PR3 at a concentration as low as 2.5 micrograms/

Proteinase‐activated receptor activation by coagulation proteinases
Drug Development Research, 2003AbstractCoagulation proteinases signal through proteinase activated receptors (PARs). Thrombin‐dependent PAR signaling on platelets is essential for hemostasis, but regulation of inflammation by PAR‐signaling is increasingly recognized as an important aspect of other pro‐ and anticoagulant pathways.

The involvement of extracellular proteinases and proteinase inhibitors in mammalian fertilization
Biotechnology and Applied Biochemistry, 1994Extracellular proteinases and proteinase inhibitors have been known to play many important roles in various biological systems. They are also important for reproductive functions of the mammals. Kallikrein stimulates human sperm motility. Porcine antithrombin III (AT III) has been identified to be a sperm-motility-stimulating protein and a ...
