Summary: Enables tropomyosin binding activity. Acts upstream of or within actin cytoskeleton organization; erythrocyte development; and positive regulation of mitotic cell cycle phase transition. Located in striated muscle thin filament. Is expressed in several structures, including alimentary system; brain; heart; metanephros; and sensory organ. Orthologous to human TMOD3 (tropomodulin 3).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
