FunctionBinds specifically to cytosolic chaperonin (c-CPN) and transfers target proteins to it. Binds to nascent polypeptide chain and promotes folding in an environment in which there are many competing pathways for nonnative proteins.
Sequence similaritiesBelongs to the prefoldin subunit alpha family.
Cellular localizationCytoplasm. Nucleus. In complex with VHL can translocate to the nucleus.
