A novel 4.1 ezrin radixin moesin (FERM)-containing protein, 'Willin'

The 4.1 superfamily of proteins contain a 4.1 ezrin radixin moesin (FERM) domain and are described as linking the cytoskeleton with the plasma membrane. Here, we describe a new FERM domain-containing protein called Willin. Willin has a recognizable FERM domain within its N-terminus and is capable of binding phospholipids. Its intra-cellular distribution can be cytoplasmic or at the plasma membrane where it can co-localize with actin. However, the plasma membrane location of Willin is not influenced by cytochalasin D induced actin disruption but it is induced by the addition of epidermal growth factor.
