    Summary
    Enables actin filament binding activity. Predicted to be involved in actin filament organization and muscle contraction. Located in cleavage furrow; cytoskeleton; and growth cone. Is expressed in coelomic epithelium of testis; ovary; and primary sex cord. Human ortholog(s) of this gene implicated in congenital myopathy 4A and nemaline myopathy 1. Orthologous to human TPM3 (tropomyosin 3). [provided by Alliance of Genome Resources, Dec 2024]

    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.

      Description
      Transcript Variant: This variant (3, also known as variant Tpm3.1) represents the use of an alternate promoter and differs in the 5' structure, causing translation initiation at an alternate start codon compared to variant Tpm3.13. The encoded isoform (Tpm3.1cy, also known as isoform 3) has a distinct N-terminus and is shorter than isoform Tpm3.13cy. Isoforms Tpm3.1cy, Tpm3.2cy, and Tpm3.5cy are the same length, but contain distinct C-termini.
