PROTEIN CHAPERONES AND THE HEAT-SHOCK RESPONSE IN SACCHAROMYCES-CEREVISIAE

Recent studies have shed new light on the complexities of the heat sho ck response in yeast. Multiple pathways for transcriptional induction of both classic and novel heat shock proteins are emerging together wi th a more detailed understanding of the interactions between protein c haperones and their physiological targets. New roles for heat shock pr oteins in defense and recovery from the impacts of thermal stress on c ritical cellular processes have expanded our understanding of these el aborate and ubiquitous proteins.
