UniProt ID: Q503D5 |
FUNCTION: Binds 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. {ECO:0000256|PIRNR:PIRNR016396}. SUBUNIT: Heterohexamer of two PFD-alpha type and four PFD-beta type subunits. {ECO:0000256|PIRNR:PIRNR016396}. SIMILARITY: Belongs to the prefoldin subunit alpha family. {ECO:0000256|ARBA:ARBA00010048, ECO:0000256|PIRNR:PIRNR016396}. |
