Enables cytoskeletal protein binding activity and small GTPase binding activity. Involved in several processes, including actin cytoskeleton organization; bicellular tight junction assembly; and substrate adhesion-dependent cell spreading. Acts upstream of or within endocytic recycling. Located in several cellular components, including actin filament bundle; bicellular tight junction; and recycling endosome. Colocalizes with stress fiber. Is expressed in several structures, including chondrocranium; liver lobe; medulla oblongata basal plate; submandibular gland primordium; and vibrissa. Orthologous to human MICALL2 (MICAL like 2). [provided by Alliance of Genome Resources, Apr 2022]
