PFN1 Antibody

Description

The dynamic polymerization and depolymerization of actin filaments, a process governed by external and internal signaling events, is vital for cell motility (immune cell function, migration, invasion, metastasis, angiogenesis), cell division and adhesion. Among the many regulators of actin dynamics are profilins. Profilins are conserved actin binding proteins that affect the rate of actin polymerization by binding actin monomers and promoting the exchange of ADP for ATP . Profilins bind to proteins involved in the regulation of actin dynamics including palladin , dynamin-1 , VASP and N-WASP . In mice, knockout of the ubiquitously expressed profilin-1 indicates that the protein is essential for embryonic development . Profilin-2 is primarily expressed in brain and functions in the regulation of neurite outgrowth , membrane trafficking and endocytosis . The recently cloned profilin-3 is expressed in kidney and testes .
