Chaperones are special proteins that assist in the proper folding and assembly of other proteins within cells. They help prevent misfolding and aggregation, which can lead to diseases. By providing a protective environment, chaperones ensure that proteins achieve their correct shapes and functions. In addition to their role in protein folding, chaperones are also involved in the transport of proteins to their appropriate locations within the cell. They can help refold damaged proteins and play a crucial role in cellular stress responses, ensuring that cells maintain their health and functionality under various conditions.
