Recombinant Human PFDN1 Protein

Product Name: Recombinant Human PFDN1 Protein
Catalog #:  HRP-0837
Manufacture:  LD Biopharma, Inc.

Eukaryotic prefoldin (PFD) is a heterohexameric chaperone with a jellyfish-like structure whose function is to deliver nonnative target proteins, principally actins and tubulins, to the eukaryotic cytosolic chaperonin for facilitated folding. Human Prefolding subunit 1 (PFDN1) gene encodes a member of the prefoldin beta subunit family. The encoded PFDN1 protein is one of six subunits of prefoldin, a molecular chaperone complex that binds and stabilizes newly synthesized polypeptides, thereby allowing them to fold correctly. The complex, consisting of two alpha and four beta subunits, forms a double beta barrel assembly with six protruding coiled-coils.

Full-length human PFDN1 (122 aa) gene was constructed with 15 aa N-terminal T7 tag and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
