Description

CUSABIO team inserts the gene coding for the Human PFN1 protein (2-140aa) into a plasmid vector to form recombinant plasmid, which is then introduced into e.coli cells. e.coli cells demonstrating successful uptake of the recombinant plasmid are selected based on their ability to survive in the presence of a specific antibiotic. The positive e.coli cells are cultured under conditions that promote the expression of the gene of interest. A N-terminal GST tag is linked to the protein. Following expression, affinity purification is used to isolate and purify the recombinant Human PFN1 protein from the cell lysate. Denaturing SDS-PAGE is then applied to resolve the resulting recombinant Human PFN1 protein, demonstrating a purity greater than 90%.

Target Background

Function
Binds to actin and affects the structure of the cytoskeleton. At high concentrations, profilin prevents the polymerization of actin, whereas it enhances it at low concentrations. By binding to PIP2, it inhibits the formation of IP3 and DG. Inhibits androgen receptor (AR) and HTT aggregation and binding of G-actin is essential for its inhibition of AR.
