Enables actin filament binding activity. Involved in several processes, including actin filament organization; regulation of actin polymerization or depolymerization; and spicule insertion. Located in striated muscle thin filament. Is expressed in several structures, including body wall musculature; germ line; intestine; non-striated muscle; and pharynx. Human ortholog(s) of this gene implicated in blood platelet disease; congenital myopathy (multiple); distal arthrogryposis type 1A; and intrinsic cardiomyopathy (multiple). Orthologous to several human genes including TPM1 (tropomyosin 1); TPM2 (tropomyosin 2); and TPM3 (tropomyosin 3).
WB Description
lev-11 encodes tropomyosin, an actin-binding contractile structural protein orthologous to human TROPOMYOSIN 1 (TPM1; OMIM:191010), which when mutated leads to familial hypertrophic cardiomyopathy; LEV-11 is required for embryonic development, normal body morphology, and locomotion; expressed as multiple tissue-specific isoforms generated by alternative mRNA splicing and promoter use, LEV-11 is detected in several tissues including muscle, pharynx, intestine, and the germ line.
