Scientists report that Hsp70s from mammalian cells behave quite differently from bacterial Hsp70s. Because of the important roles Hsp70s play in protein misfolding diseases such as cancer and neurodegenerative diseases, the new findings 'will have a major impact on how we think about Hsp70s,' one of the researchers says.
