HRP-1303 Recombinant Human Profiling-1 Protein $300

Recombinant Human Profiling-1 Protein

Product Name: Recombinant Human Profiling-1 Protein
Catalog #:  HRP-1303
Manufacture:  LD Biopharma, Inc.

Human profiling 1 (PFN1) gene encodes a member of the profilin family of small actin-binding proteins. The encoded protein plays an important role in actin dynamics by regulating actin polymerization in response to extracellular signals. By binding to PIP2, PFN1 inhibits the formation of IP3 and DG. It also inhibits androgen receptor (AR) and HTT aggregation and binding of G-actin is essential for its inhibition of AR. Deletion of this gene is associated with Miller-Dieker syndrome, and the encoded protein may also play a role in Huntington disease. Multiple pseudogenes of this gene are located on chromosome 1.

Full-length human PFN1 cDNA (2 – 140 aa) was constructed with codon optimization 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. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
