Predicted to enable actin filament binding activity. Predicted to be involved in actin filament organization. Predicted to act upstream of or within several processes, including columnar/cuboidal epithelial cell development; neural tube closure; and regulation of cell shape. Predicted to be located in apical part of cell and cytoskeleton. Predicted to be active in several cellular components, including adherens junction; apical junction complex; and apical plasma membrane. Orthologous to human SHROOM3 (shroom family member 3).
