Prefoldin binds and stabilizes newly synthesized polypeptides allowing them to fold correctly. The hexameric structure consists of a double beta barrel assembly with six protruding coiled-coils. The alpha prefoldin subunits have two beta hairpin structures while the beta prefoldin subunits (this CD) have only one hairpin that is most similar to the second hairpin of the alpha subunit. The prefoldin hexamer consists of two alpha and four beta subunits and is assembled from the beta hairpins of all six subunits. The alpha subunits initially dimerize providing a structural nucleus for the assembly of the beta subunits. In archaea, there is usually only one gene for each subunit while in eukaryotes there two or more paralogous genes encoding each subunit adding heterogeneity to the structure of the hexamer.

Eukaryotic PFD is a multi-subunit complex containing six polypeptides in the molecular mass range of 14-23 kDa. In archaea, on the other hand, PFD is composed of two types of subunits, two alpha and four beta. The six subunits associate to form two back-to-back up-and-down eight-stranded barrels, from which hang six coiled coils. Each subunit contributes one (beta subunits) or two (alpha subunits) beta hairpin turns to the barrels. The coiled coils are formed by the N and C termini of an individual subunit. Overall, this unique arrangement resembles a jellyfish. The eukaryotic PFD hexamer is composed of six different subunits; however, these can be grouped into two alpha-like (PFD3 and -5) and four beta-like (PFD1, -2, -4, and -6) subunits based on amino acid sequence similarity with their archaeal counterparts. Eukaryotic PFD has a six-legged structure similar to that seen in the archaeal homologue [, ]. This family contains the archaeal beta subunit, eukaryotic prefoldin subunits 1, 2, 4 and 6. Eukaryotic PFD has been shown to bind both actin and tubulin co-translationally. The chaperone then delivers the target protein to CCT, interacting with the chaperonin through the tips of the coiled coils.
