Abstract
Although longstanding experimental evidence has associated alterations
of calcium homeostasis to cell death, only in the past few years
the role of calcium in the signaling of apoptosis has been extensively
investigated. In this review, we will summarize the current knowledge,
focusing on (i) the effect of the proteins of the Bcl-2 family on
ER Ca$^2+$ levels, (ii) the action of the proteolytic enzymes
of apoptosis on the Ca$^2+$ signaling machinery, (iii) the ensuing
alterations on the signaling patterns of extracellular stimuli, and
(iv) the intracellular targets of 'apoptotic' Ca$^2+$ signals,
with special emphasis on the mitochondria and cytosolic Ca$^2+$-dependent
enzymes.
