Binds to actin and affects the structure of the cytoskeleton. Additionally we are shipping Profilin 4 Proteins (14) and Profilin 4 Kits (3) and many more products for this protein.
Showing 5 out of 9 products:
PRF4 and PRF5 regulate actin polymerization in pollen grains and tubes.
Porfilin 4 bound to selected phosphoinositides but not to poly-L-proline, proline-rich proteins, or actin.
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. Has a high affinity for poly-proline.
