True about chaperone?
Ans. is 'a' i.e., Also known as HS proteinsChaperones are proteins which help in folding or unfolding of proteins Molecular chaperones prevent aggregation and promote refolding after stress and hence promote cell survival. This so-called stress response is ubiquitous and conserved across all organisms. Hence Chaperones are otherwise known as heat shock proteins (HSP)Chaperones are synthesized in response to heat and other stress conditions like exposure to heavy metals, UV radiation, oxidative stress, nutrient deficiencies, dehydration, osmotic pressures and viral infections. Hence, they are otherwise called as stress proteins
Also known as HS proteins
Have ATPase activity
Always bind to specific areas on unfolded proteins
They always acts as foldases
