Several key players are involved in the protein import process:
Signal Peptides: Short sequences that direct the protein to the appropriate organelle. Receptors: Proteins that recognize signal peptides and facilitate the initial binding of the protein to the organelle membrane. Translocons: Complexes that form channels through which proteins are transported across membranes. Chaperones: Proteins that assist in the folding and unfolding of proteins during import to prevent aggregation.
