Secondary 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 |
