Predicted to enable tropomyosin binding activity. Predicted to be involved in actin filament organization; muscle contraction; and myofibril assembly. Predicted to act upstream of or within actin cytoskeleton organization; erythrocyte development; and positive regulation of mitotic cell cycle phase transition. Predicted to be active in striated muscle thin filament. Orthologous to human TMOD3 (tropomodulin 3). [provided by Alliance of Genome Resources, Apr 2022]
