Abstract
The budding yeast Saccharomyces cerevisiae, a favorite model in biology, does not contain any protein of the Bcl-2 family. From initial experiments with two-hybrid systems to the heterologous expression of human Bcl-2 family members, and the characterization of several forms of yeast programmed cell death, it has however always been a powerful tool to gain information on the mechanisms of apoptosis in general and on Bcl-2 family in particular. This is a short survey of 25 years of experiments that have provided, and at times initiated, insights into the molecular mechanisms underlying the function of Bcl-2 family members.
