    Summary
    Enables actin filament binding activity; protein heterodimerization activity; and protein homodimerization activity. Predicted to be involved in actin filament organization; muscle contraction; and regulation of ATPase activity. Located in actin cytoskeleton. Human ortholog(s) of this gene implicated in distal arthrogryposis type 1A and nemaline myopathy 4. Orthologous to human TPM2 (tropomyosin 2). [provided by Alliance of Genome Resources, Apr 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: VALIDATED

      Description
      Transcript Variant: This variant (Tpm2.1, also known as variant 2) has an alternate internal exon and an alternate 3' exon, as compared to variant Tpm2.2. The resulting isoform (Tpm2.1sm/cy, also known as isoform 2) has a different internal segment and a different C-terminus, but has the same protein size, as compared to isoform Tpm2.2st.
