Function
Moesin (Membrane-Organizing Extension Spike Protein) is a member of the ERM family (Ezrin-Radixin-Moesin) which is important for organizing membrane domains of effector T cells[1]. It plays a role in modification of the actin cytoskeleton[2].
Disease
Moesin is involved in the regulation of cell adhesion, polarity and migration by cross-linking between the actin cytoskeleton and plasma membrane and thus regulates hepatic fibrosis[3].
Relevance
Reduction of moesin expression in Drosophila brain resulted in prevention of long term memory formation.
Structural highlights
The 3D structure of the complex between FERM domain of the actin-binding moesin and the C-tail domain of cell polarity protein Crumbs shows that the interaction between the 2 proteins involves very few residues[4].
