WebbIn conclusion, secondary structure, thermostability and unfolding behaviour of the two cytoplasmic isoforms of human Hsp90 were compared. Although the two proteins exhibit a secondary structure of very high similarity, the stress-inducible isoform Hsp90α shows a significantly higher thermal stability than the constitutive Hsp90β. WebbHeat shock proteins 90 (Hsp90) are chaperones that promote the proper folding of other proteins under high temperature stress situations. Hsp90s are highly conserved and ubiquitous proteins, and in mammalian cells, they are localized in the cytoplasm, endoplasmic reticulum, and mitochondria. Cytopla …
