WebbCaspases, closely associated with apoptosis, are aspartate-specific cysteine proteases and members of the interleukin-1beta-converting enzyme family. The activation and function of caspases, involved in the delicate caspase-cascade system, are regulated by various kinds of molecules, such as the inhibitor of apoptosis protein, Bcl-2 family proteins, calpain, … WebbApoptotic protease activating factor-1 (Apaf-1) is an adaptor molecule, essential for activating initiator caspase and downstream effector caspases, which directly cause apoptosis. In fruit flies, nematodes, and mammals, Apaf-1 has been extensively studied. However, the structure and function of Apaf-1 in Lepidoptera remain unclear.

WebbThe activation of the complement cascade by any of the three pathways leads to the formation of central enzymatic complexes C4b2b and C3bBb convertases. Through their serine-protease activity, the C3 convertases are capable to cleave the C3 molecule nearby into its bioactive form C3b and C3a, an anaphylatoxin. WebbA proteolytic cascade orchestrated by a parasite serine protease, subtilisin-like protease 1 (SUB1), regulates the membrane breakdown. SUB1 activation involves primary … Webb13 nov. 2009 · Introduction The newly uncovered epithelial extracellular proteolytic activation cascade has to date only two members: matriptase (PRSS14), a type-II transmembrane serine protease, and prostasin (PRSS8), a glycosylphosphatidylinositol (GPI)-anchored serine protease [ 1 ]. tpl0346

Webb12 jan. 1999 · These death proteases are part of a proteolytic caspase cascade that is activated by diverse apoptotic stimuli from outside and inside of the cell. WebbAspartate-specific cysteine proteases, the so-called ‘caspases’, are the main enzymes involved in this process. At least ten homologues of interleukin-1β converting enzyme (ICE), the first described human caspase, have been identified so far.
