Activity summary

The groES protein also known as Hsp10 plays a mechanical role as a molecular chaperone. It partners with the groEL protein to facilitate the correct folding of other proteins. The groES protein has a mass of approximately 10 kDa and is universally expressed across a wide range of species from prokaryotes to eukaryotes. It comprises a heptameric ring structure that caps the groEL complex making it critical in the chaperonin cycle. groES specifically binds to the groEL protein assisting in the folding of unfolded or misfolded substrates within the cellular environment.

Biological function summary

The groES protein functions within a chaperonin complex alongside groEL to prevent aggregation and promote proper protein folding. This complex plays a significant role in cellular stress response and stabilization of proteins especially under heat shock conditions. The chaperonin system refolds denatured proteins and maintains proteostasis ensuring efficient cellular function. The groES and groEL interaction facilitates timed ATP hydrolysis which is necessary for the release of correctly folded proteins back into the cellular environment.

Pathways

GroES integrates into cellular stress response and protein quality control pathways. It is important in the protein processing pathway alongside groEL and Hsp70 enabling effective folding of nascent polypeptides. GroES and these chaperones serve as emergency machinery to protect the cell during adverse conditions such as thermal or oxidative stress. Together they prevent cellular damage caused by protein misfolding which may otherwise lead to cytotoxicity or cell death.

Associated diseases and disorders

The groES protein has connections to various pathologies linked to protein misfolding and aggregation such as neurodegenerative diseases. Specifically its function relates to conditions like Alzheimer's and Parkinson's disease where protein folding malfunctions play an important role. The interaction between groES and proteins like groEL and Hsp70 is pivotal in preventing the accumulation of misfolded protein aggregates associated with these disorders. Targeting the chaperonin system has become a potential strategy in managing diseases where maintaining proteostasis mitigates cellular dysfunction.
