Gene Information

human ... FOLH1(2346)

General description

FOLH1 (folate hydrolase 1) is a type II membrane protein, which is composed of a cytosolic domain, a transmembrane region, and an exoplasmic region. This protein exhibits both constitutive and induced internalization. It is an exopeptidase, which is Zn-dependent and is localized on the brush-border of the intestine.

Immunogen

Glutamate carboxypeptidase 2 recombinant protein epitope signature tag (PrEST)

Application

Anti-FOLH1 antibody produced in rabbit has been used for FACS (flourescence activated cell sorting)-based epitope mapping. Anti-FOLH1 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 sigma.com/prestige.

Biochem/physiol Actions

FOLH1 (folate hydrolase 1) is also known as prostate-specific membrane antigen (PSMA) and is over and strongly expressed in prostate cancer cells, including metastatic cells. This protein functions both as an N-acetylated a-linked acidic dipeptidase (NAALADase) and folate hydrolase (FOLH). In small intestine, it is responsible for the absorption of dietary polyglutamylated folates (folyl-n-γ-l-glutamic acid), which are the provitamin form of folic acid. Variants in this gene are linked with folate nutritional status and disease susceptibility, and its interaction with dietary natural vitamin C might be linked with the susceptibility to adenomatous polyp.

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.

The C1561T variant of the glutamate carboxypeptidase II (GCPII) gene is critical for natural methylfolylpolyglutamte (methylfolate) absorption, and has been associated with perturbations in folate metabolism and disease susceptibility. However, little is known on C1561T-GCPII as a risk factor for
