Mechanisms of caspase activation.
The core effectors of apoptosis encompass proteolytic enzymes of the caspase family, which reside as latent precursors in most nucleated metazoan cells. A majority of studies on apoptosis are based on the assumption that caspase precursors are activated by cleavage, a common mechanism for most protease zymogen activations. Although this appears to be true for the executioner caspases, recent re...
متن کاملAVEN (apoptosis, caspase activation inhibitor)
Review on AVEN, with data on DNA/RNA, on the protein encoded and where the gene is implicated.
متن کاملHuntingtin inhibits caspase-3 activation.
Huntington's disease results from a mutation in the HD gene encoding for the protein huntingtin. The function of huntingtin, although beginning to be elucidated, remains largely unclear. To probe the prosurvival function of huntingtin, we modulate levels of wild-type huntingtin in a number of cellular and in vivo models. Huntingtin depletion resulted in caspase-3 activation, and overexpression ...
متن کاملCaspase activation cascades in apoptosis.
Apoptosis, a highly controlled mode of cell death, is utilized to eliminate superfluous, aged, injured or infected cells from the body. Caspases, a family of aspartic acid-specific proteases, are the major effectors of apoptosis. To curtail their activity, caspases are normally synthesized as inactive precursors, but become activated at the onset of apoptosis by activation signals. Once active,...
متن کاملCaspase activation: the induced-proximity model.
Members of the caspase family of proteases transmit the events that lead to apoptosis of animal cells. Distinct members of the family are involved in both the initiation and execution phases of cell death, with the initiator caspases being recruited to multicomponent signaling complexes. Initiation of apoptotic events depends on the ability of the signaling complexes to generate an active prote...
