Gene Information

human ... TPM3(7170)

General description

TPM3 (tropomyosin 3) gene is localized to human chromosome 1q21.3, and codes for an actin-binding protein. It is present in skeletal and smooth muscles, as well as certain non-muscular tissues. It functions as an oncogene.

Biochem/physiol Actions

TPM3 (tropomyosin 3) is involved in the stabilization of cytoskeleton microfilaments. Upon induction by Ca2+ in skeletal muscles, it mediates the actin-myosin response. However, its function in non-muscular cells is still not clear. TPM3-ALK (anaplastic lymphoma receptor tyrosine kinase) fusion through (1;2) translocation results in hematopoietic tumorigenesis. Fusion with NTRK1 and PDGFRB genes results in the induction of papillary thyroid carcinoma and chronic eosinophilic leukemia. It is responsible for the migration and invasion in hepatocellular carcinoma by facilitating EMT (epithelial-mesenchymal transition) in a Snail-dependent manner. Expression of this protein in tumors is positively linked with the expression of MMP (matrix metalloproteinases). Hence, this protein plays a key role in the progression of gliomas. Mutations in this gene are responsible for the neuromuscular defects in patients with congenital myopathy with fibre type disproportion (CFTD).

Features and Benefits

Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.

Every Prestige Antibody is tested in the following ways:
  • IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
  • Protein array of 364 human recombinant protein fragments.


Corresponding Antigen APREST70731.
