Prefoldin subunit 3; Prefoldin subunit 3 is one of the alpha subunits of the eukaryotic prefoldin complex. Prefoldin is a hexameric molecular chaperone complex, found in both eukaryotes and archaea, that binds and stabilizes newly synthesized polypeptides allowing them to fold correctly. The complex contains two alpha and four beta subunits, the two subunits being evolutionarily related. 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. The structure of the complex consists of a double beta barrel assembly with six protruding coiled-coils.

Prefoldin subunit; This family comprises of several prefoldin subunits. The biogenesis of the cytoskeletal proteins actin and tubulin involves interaction of nascent chains of each of the two proteins with the oligomeric protein prefoldin (PFD) and their subsequent transfer to the cytosolic chaperonin CCT (chaperonin containing TCP-1). Electron microscopy shows that eukaryotic PFD, which has a similar structure to its archaeal counterpart, interacts with unfolded actin along the tips of its projecting arms. In its PFD-bound state, actin seems to acquire a conformation similar to that adopted when it is bound to CCT.

protein UXT; UXT is an alpha subunit of the prefoldin-like complex (PFDL). PFDL is involved in the cytoplasmic assembly of RNA polymerase I and can interact with other chaperone complexes, like R2TP, to form the PAQosome. UXT has an important role in the activation of the NF-kappaB pathway. UXT is also a component of the centrosome and is associated with gamma-tubulin. Prefoldin is a hexameric molecular chaperone complex, found in both eukaryotes and archaea, that binds and stabilizes newly synthesized polypeptides allowing them to fold correctly. The complex contains two alpha and four beta subunits, the two subunits being evolutionarily related.
