Predicted to enable GTPase binding activity. Predicted to be involved in several processes, including plasma membrane tubulation; positive regulation of filopodium assembly; and vesicle transport along actin filament. Predicted to act upstream of or within cilium assembly. Predicted to be located in cytoplasmic vesicle and cytosol. Orthologous to human FNBP1L (formin binding protein 1 like).
