proteostasis

/ˌprəʊ.ti.əʊˈsteɪ.sɪs/
IELTSAcademic
noun

The balance and control of proteins inside a living cell or body. It means making proteins correctly, keeping them working, and removing broken ones.

  • Proteostasis helps cells stay healthy.
  • Bad proteostasis can damage body cells.
  • Scientists study proteostasis in aging and disease.

Adinary Nuance

Proteostasis is broader than protein folding. Protein folding is only one part of the process, while proteostasis includes making, folding, checking, repairing, and removing proteins. It is also wider than protein homeostasis, which is a close near-neighbor and often used in similar scientific contexts. Writers usually choose proteostasis when they want to name the full cell system, not just one step.
