Predicted to enable actin filament binding activity; beta-catenin binding activity; and protein domain specific binding activity. Predicted to be involved in actin filament organization; cell migration; and melanosome organization. Predicted to act upstream of or within cell-cell junction maintenance and negative regulation of actin filament depolymerization. Predicted to be located in several cellular components, including bicellular tight junction; cell cortex; and neuronal cell body. Predicted to be active in several cellular components, including adherens junction; apical junction complex; and apical plasma membrane. Orthologous to human SHROOM2 (shroom family member 2).
