Enables actin binding activity and tropomyosin binding activity. Predicted to be involved in actin filament organization; muscle contraction; and myofibril assembly. Predicted to act upstream of or within learning or memory; neuron-neuron synaptic transmission; and positive regulation of G protein-coupled receptor signaling pathway. Located in growth cone. Orthologous to human TMOD2 (tropomodulin 2). [provided by Alliance of Genome Resources, Apr 2022]
