Chaperones are specialized proteins that assist in the proper folding of other proteins within cells. They help prevent misfolding and aggregation, which can lead to cellular dysfunction and diseases. By providing a protective environment, chaperones ensure that proteins achieve their correct three-dimensional structures. In addition to aiding in protein folding, chaperones also play a role in the transport of proteins to their appropriate locations within the cell. They can help refold damaged proteins or target them for degradation if they are beyond repair. This process is crucial for maintaining cellular health and function, particularly in complex organisms like humans.
