HTF-1536 Recombinant Human PFND5 Protein $300

Recombinant Human PFND5 Protein

Product Name: Recombinant Human PFND5 Protein
Catalog #:  HTF-1536
Manufacture:  LD Biopharma, Inc.

Human prefoldin subunit 5 (PFDN5) gene encodes a member of the prefoldin alpha subunit family. The encoded 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. The encoded protein may also repress the transcriptional activity of the proto-oncogene c-Myc. Alternatively spliced transcript variants encoding different isoforms have been described.

Full-length human PFDN5 cDNA (153aa, Isoform-alpha) was constructed with codon optimization technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal. This protein is expressed in E.coli as inclusion bodies. It was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
