We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

| - | '''Profilin''' (PFN) enhances actin growth by binding to monomeric actin, thus becoming profilactin. PFN catalyzes the exchange of poorly polymerizing ADP-actin to readily polymerizing ATP-actin. PFN binds to poly-L-proline, thus it recruits the actin monomers to proline-rich proteins like VASP, which enhance the growing of actin polymers. PFN-I is expressed in most tissues while PFN-II is expressed in brain and kidney. PFN was found in all eukaryotes. | ||
