Caspases in developmental cell death.
Caspases are a family of evolutionarily conserved cysteine proteases that constitute the effector arm of the apoptotic machinery. Studies in Caenorhabditis elegans, Drosophila melanogaster, and mouse point to evolutionarily conserved caspase function in developmentally programmed cell death in metazoans. Whereas in the nematode all developmental cell death is mediated by a single caspase, in Drosophila and the mouse some caspases appear to regulate cell death in a spatio-temporally restricted manner. This article reviews what we currently know about the roles of various caspases in the execution of developmentally programmed cell death and what may be expected from future research in this field.
