Summary: Enables cytoskeletal anchor activity and structural molecule activity. Involved in several processes, including actin filament organization; nematode larval development; and protein localization to basolateral plasma membrane. Located in several cellular components, including actin filament; apical cortex; and apical plasma membrane. Is expressed in several structures, including anal sphincter muscle; excretory cell; intestine; nervous system; and reproductive system. Human ortholog(s) of this gene implicated in autosomal recessive nonsyndromic deafness 24 and immunodeficiency 50. Orthologous to several human genes including EZR (ezrin) and MSN (moesin).

C-terminal phosphorylation modulates ERM-1 localization and dynamics to control cortical actin organization and support lumen formation during Caenorhabditis elegans development.
Title: C-terminal phosphorylation modulates ERM-1 localization and dynamics to control cortical actin organization and support lumen formation during Caenorhabditiselegans development.
We evidence that wild-type ezrin (ezrinWT) and its phosphomimetic mutant T567D (ezrinTD) do not deform membranes but self-assemble anti-parallelly, zipping adjacent membranes. EzrinTD's specific conformation reduces intermolecular interactions, allows binding to actin filaments, which reduces membrane tethering, and promotes ezrin binding to positively-curved membranes.
Title: Ezrin enrichment on curved membranes requires a specific conformation or interaction with a curvature-sensitive partner.
fortifying the link between the apical membrane and actin cortex by overexpression of the ezrin/radixin/moesin ortholog ERM-1, significantly rescued cyst formation and ruptures in the pigv-1(qm34) mutant.
Title: Glycosyl phosphatidylinositol anchor biosynthesis is essential for maintaining epithelial integrity during Caenorhabditis elegans embryogenesis.
ERM-1 prevents the immediate activation of the entire pool of LET-23 EGFR and permits the generation of a long-lasting inductive signal
Title: An in vivo EGF receptor localization screen in C. elegans Identifies the Ezrin homolog ERM-1 as a temporal regulator of signaling.
Propose that the ERM-1/AQP-8 interaction propels lumen extension by translumenal flux, suggesting a direct morphogenetic effect of water-channel-regulated fluid pressure.
Title: Intracellular lumen extension requires ERM-1-dependent apical membrane expansion and AQP-8-mediated flux.
The novel intestinal filament organizer IFO-1 contributes to epithelial integrity in concert with ERM-1 and DLG-1.
Title: The novel intestinal filament organizer IFO-1 contributes to epithelial integrity in concert with ERM-1 and DLG-1.
Genetic analysis indicates that mig-15 and erm-1 act in the same genetic pathway to regulate growth cone migration, and this pathway functions in parallel to the UNC-116/WVE-1 pathway.
Title: MIG-15 and ERM-1 promote growth cone directional migration in parallel to UNC-116 and WVE-1.
ERM-1 localizes to the luminal membranes of tubular organ epithelia which lack stabilization by cuticle. RNAi, a germline deletion, and overexpression of erm-1 cause cystic luminal phenotypes in these epithelia.
Title: Lumen morphogenesis in C. elegans requires the membrane-cytoskeleton linker erm-1.
ERM-1 is the first protein of the apical membrane domain affecting junction remodelling in C. elegans
Title: The C. elegans ezrin-radixin-moesin protein ERM-1 is necessary for apical junction remodelling and tubulogenesis in the intestine.
The ERM proteins ezrin and moesin were found to strongly co-localise with both ICAM-1 and F-actin in brain microvascular endothelial cells suggesting a potential role in mediating ICAM-1 signalling.
Title: Ezrin and moesin co-localise with ICAM-1 in brain endothelial cells but are not directly associated.
