Anti-TM4SF1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit

Biochem/physiol Actions

Transmembrane 4 L6 family member 1 is a protein encoded by the TM4SF1 gene in humans. It is a cell surface antigen, which is highly expressed in lung, breast, colon and ovarian carcinomas. It has a novel function in Androgen Receptor (AR) signaling. Its mRNA expression is higher in prostate cancer tissues as compared to benign prostatic hyperplasia (BPH). It is found to contribute to prostate cancer cell metastasis. The gene serves as a molecular organizer that interacts with membrane and cytoskeleton-associated proteins. It uniquely initiates the formation of nanopodia and facilitates cell polarization and migration. It also regulates tumour cell motility and invasiveness. It is abundant on the plasma membrane and on intracellular vesicles.

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.
