The interleukin-1 beta-converting enzyme (ICE)-like family proteases have recently been identified as key enzymes in apoptotic cell death. Among these proteases one can identify specific activities which may be involved in cytokine production or in resident protein cleavage. Several factors influence the constitutive apoptotic mechanism and may provide

Proteases and Protease Inhibitors in Neoplasia
1974Although proteases in tumours have been studied for many years [1], their role is far from clear. From a number of comparative studies (summarized in Table 1), however, it can be safely concluded that increased proteolytic activity is often associated with tumours.

AAA+ proteases: ATP-fueled machines of protein destruction.
Annual Review of Biochemistry, 2011AAA+ family proteolytic machines (ClpXP, ClpAP, ClpCP, HslUV, Lon, FtsH, PAN/20S, and the 26S proteasome) perform protein quality control and are used in regulatory circuits in all cells. These machines contain a compartmental protease, with active sites

Characterization of proteases and protease inhibitors in the rat stomach
American Journal of Physiology-Gastrointestinal and Liver Physiology, 1997Previously our laboratory reported increased activity of the thiol proteinase cathepsin B in gastric juice after ethanol-induced mucosal injury. In this study we measured proteinase activity (PA) and proteinase inhibitory activity (PIA) with the general substrates hemoglobin, azocasein, and bovine serum albumin (BSA) at optimal pH (2.0, 5.6, and 7.4 ...

Proteases and Protease Inhibitors in Male Reproduction
2017From the development of the spermatozoa within the seminiferous tubule of testis to the fertilization events that occur in female reproductive tract, all the reproductive processes in mammals are regulated by a highly orchestrated and integrative mechanism. Several proteases and their protease inhibitors form an important part of this mechanism. So far,

Publisher Summary This chapter focuses on non-digestive proteases, which have many diverse roles in insect biology. Proteases (peptidases) are enzymes that hydrolyze peptide bonds in proteins. These proteases often function in cascade pathways, in which one protease activates the zymogen form of another protease, leading to amplification of an initial
