Predicted to enable actin monomer binding activity. Acts upstream of or within cilium assembly and embryonic organ morphogenesis. Predicted to be located in several cellular components, including cytoskeleton; cytosol; and ruffle. Is expressed in several structures, including Kupffer's vesicle; midbrain hindbrain boundary neural rod; nervous system; pronephros; and trunk. Orthologous to human COBL (cordon-bleu WH2 repeat protein).
