The Patched dependence receptor triggers apoptosis through a DRAL–caspase-9 complex
Shh acts as a survival factor and in its absence its receptor, Patched, induces cell death by recruiting a caspase-activating complex formed by the adaptor protein DRAL, the CARD domain containing proteins TUC...

Yeast and apoptosis
Even though yeast lack much of the molecular machinery that is responsible for apoptosis in metazoans, they can be a powerful tool in apoptosis research. The ectopic expression of several animal apoptosis prot...

Molecular chaperone targeting and regulation by BAG family proteins
Regulated changes in protein conformation can have profound effects on protein function, although routine laboratory methods often fail to detect them. The recently discovered BAG-family proteins may operate a...

Changes in intramitochondrial and cytosolic pH: early events that modulate caspase activation during apoptosis
Mitochondria trigger apoptosis by releasing caspase activators, including cytochrome c (cytC). Here we show, using a pH-sensitive green fluorescent protein (GFP), that mitochondria-dependent apoptotic stimuli (su...

Survivin’ cell-separation anxiety
Survivin, a cell-death inhibitor, localizes to the spindles of mitotic cells, and its absence causes both a failure in cell division and induction of cell death. Might survivin link the control of cell death w...
