Secondry Information

Presence in other biological fluids/tissue/cells bovine uterus smooth muscle cells, microvilli, filopodia, uropods, ruffling membranes, retraction fibers, the cleavage furrow of dividing cells, and adhesion sites where actin filaments are associated with the plasma membrane
Protein Function heparin-binding protein; interacted with CD43; increased expression is necessary during epithelial-mesenchymal transition for efficient actin filament remodeling, and for cortical relocalization of adhesion and contractile elements
Biochemical Properties an N-terminal membrane binding domain (FERM domain), which can bind the membrane via phosphatidylinositol (4,5)-bisphosphate (PIP2), a α-helical linker region and a C-terminal actin-binding domain; Moesin and ezrin show similar affinities for PIP2; both ezrin and moesin were more rapidly degraded by chymotrypsin after binding to PIP2-LUVs
Significance in milk Ezrin-radixin-moeisin binding phosphoprotein is required for the development of lactating mammary glands
Additional Comments high degree of homology among ERM members; tissue distribution and primary structures are different for the ERM proteins; of all ERM proteins, moesin is the only one present in platelets
