Predicted to enable tropomyosin binding activity. Involved in several processes, including myofibril assembly; nematode larval development; and pointed-end actin filament capping. Located in striated muscle thin filament and terminal web. Expressed in intestine; pharyngeal muscle cell; seam cell; spermatheca; and uterine muscle. Human ortholog(s) of this gene implicated in dilated cardiomyopathy 2G; megacystis-microcolon-intestinal hypoperistalsis syndrome; and nemaline myopathy 10. Is an ortholog of several human genes including TMOD1 (tropomodulin 1); TMOD3 (tropomodulin 3); and TMOD4 (tropomodulin 4).
