Heat shock proteins (HSPs)
nounPronunciation: /ˈhiːt ʃɑːk ˈproʊtinz/
A class of molecular chaperone proteins induced by elevated temperatures and other stress conditions that protect cellular proteins from denaturation and aggregation. HSPs facilitate protein refolding and maintain cellular proteostasis during thermal and oxidative stress.
Plain English
Protective proteins produced by plants during heat stress that prevent other proteins from being damaged.
Etymology & History
Usage
"Heat shock proteins were upregulated within minutes of temperature elevation, protecting essential metabolic enzymes from thermal denaturation."
Style guide notes: Use 'heat shock proteins' when introducing term; 'HSPs' is acceptable abbreviation thereafter.

Frequently Asked Questions
At what temperature are HSPs typically induced in plants?
HSPs are induced when temperatures exceed normal growing range by 5-10°C.
What is the main function of HSPs during stress?
HSPs prevent protein misfolding and aggregation, maintaining cellular function.
Why Test Candidates on This?
Frequently examined in molecular stress physiology and thermal tolerance research.
