Is an ortholog of human MSN (moesin) and rdx. Exhibits structural molecule activity. Is involved in several processes, including actin filament organization\; morphogenesis of an epithelium\; and nematode larval development. Localizes to the apical cortex\; apical plasma membrane\; and membrane-enclosed lumen. Colocalizes with the filamentous actin. Is expressed in the PVDL\; the PVDR\; the uterine toroidal epithelial cell\; and the vulval precursor cell. Human ortholog(s) of this gene are implicated in autosomal recessive nonsyndromic deafness 24.
