    Summary
    This gene is a member of the tropomyosin family of highly conserved, widely distributed actin-binding proteins involved in the contractile system of striated and smooth muscles and the cytoskeleton of non-muscle cells. Tropomyosin is composed of two alpha-helical chains arranged as a coiled-coil. It is polymerized end to end along the two grooves of actin filaments and provides stability to the filaments. The encoded protein is one type of alpha helical chain that forms the predominant tropomyosin of striated muscle, where it also functions in association with the troponin complex to regulate the calcium-dependent interaction of actin and myosin during muscle contraction. In smooth muscle and non-muscle cells, alternatively spliced transcript variants encoding a range of isoforms have been described. Mutations in this gene are associated with type 3 familial hypertrophic cardiomyopathy and dilated cardiomyopathy 1Y. [provided by RefSeq, Jun 2022]

    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.

      Status: REVIEWED

      Description
      Transcript Variant: This variant (Tpm1.2, also known as variant 8) contains an alternate, in-frame exon in the 5' coding region, compared to variant Tpm1.1. It encodes isoform Tpm1.2st, which has a distinct N-terminus, compared to isoform Tpm1.1st.

      Description
      Transcript Variant: This variant (Tpm1.8, also known as variant 9) contains alternate in-frame exons in the 5' and 3' coding region, compared to variant Tpm1.1. It encodes isoform Tpm1.8cy, which has distinct N- and C-termini and is shorter than isoform Tpm1.1st. Variants Tpm1.8, Tpm1.9 and Tpm1.13 encode isoforms that are the same length, but have distinct protein sequences.
