Ezrin also known as cytovillin or villin-2 is a protein that in humans is encoded by the EZR gene.[1]

The cytoplasmic peripheral membrane protein encoded by this gene functions as a protein-tyrosine kinase substrate in microvilli. As a member of the ERM protein family, this protein serves as an intermediate between the plasma membrane and the actin cytoskeleton. It plays a key role in cell surface structure adhesion, migration, and organization.[2]

The N-terminal half of ezrin contains an FERM domain, which interacts with phosphatidylinositol(4,5)bis-phosphate (PIP2)and membrane proteins like CD44 and ICAM-2. The C-terminal half contains three subdomains: a domain which strongly binds sodium-hydrogen exchanger regulatory factor (NHERF) proteins, a conserved actin-binding domain, and an FERM-interacting domain.
