A protein that assists other proteins in achieving their correct folded structure without being part of the final structure. Chaperones prevent misfolding and aggregation during protein synthesis and stress conditions.
Named by analogy to human chaperones who supervise and protect without becoming romantically involved. The term was coined in the 1980s when scientists discovered proteins that helped others fold properly without becoming part of the final structure.
These are the ultimate molecular babysitters - they help other proteins get dressed properly but never stick around for the party! Some chaperones even have the ability to rescue misfolded proteins and give them a second chance at life.
The term 'chaperone' derives from the historical practice of older women supervising young unmarried women. Applied to proteins in 1989, it retains the gendered metaphor of protective female guardianship without recognition that this framing may conflate care work with biological function.
Use the word scientifically (it's established nomenclature), but recognize the metaphor as descriptive convenience rather than explanatory—the protein's mechanism is assistance with folding, not literal guardianship.

The metaphor overlooks that actual chaperones performed invisible reproductive labor. In scientific naming, acknowledge this as linguistic convention rather than functional description.
