Predicted to enable actin filament binding activity and actin monomer binding activity. Predicted to be involved in several processes, including cholesterol homeostasis; intestinal cholesterol absorption; and negative regulation of actin filament depolymerization. Predicted to be located in several cellular components, including brush border membrane; focal adhesion; and stress fiber. Predicted to be active in actin cytoskeleton and plasma membrane. Orthologous to human LIMA1 (LIM domain and actin binding 1). [provided by Alliance of Genome Resources, Apr 2022]
