heat-shock protein

…of heat stress, ectotherms release heat-shock proteins, which help stabilize other proteins and thus prevent their denaturation (modification of a protein’s molecular structure).

…Stanley Meselson, Lindquist learned of heat-shock proteins—proteins synthesized rapidly and in large quantities following cellular exposure to sudden increases in temperature. Throughout the 1980s and ’90s, Lindquist explored heat-shock proteins in various model organisms, including the fruit fly Drosophila melanogaster, the yeast Saccharomyces cerevisiae, and the flowering plant Arabidopsis thaliana.…
