## Abstract Synthesis of a family of proteins called βheat shockβ proteins is enhanced in cells in response to a wide variety of environmental stresses. This suggests that these proteins may have functions essential to cell survival under stressful conditions. A causative relationship between heat
During 4 hr after puromycin (PUR: 20 pg/ml) treatment, the synthesis of three major heat shock protein families (HSPs: M, = 110,000,87,000, and 70,000) was enhanced 1.5-fold relative to that of untreated cells, as studied by one-dimensional gel electrophoresis. The increase of unique HSPs, if studie
