Gene Information

human ... ASS1(445)

General description

The gene ASS1 (argininosuccinate synthase) is mapped to human chromosome 9q34.1. It is widely expressed in human tissues.

Immunogen

Argininosuccinate synthase recombinant protein epitope signature tag (PrEST)

Application

Anti-ASS1 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

ASS1 (argininosuccinate synthase) is mainly responsible for conversion of citrulline and aspartate into argininosuccinate. The pathway is crucial in the urea and arginine-citrulline cycles. Mutations in ASS1 are associated with citrullinemia. ASS1 is down-regulated by promoter methylation in children suffering from phenylketonuria (PKU). Aberrant expression of ASS1 is associated with carcinogenesis of gastric cancer.

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.

In the tumor microenvironment, arginine is metabolized by arginase-expressing myeloid cells. This arginine depletion profoundly inhibits T cell functions and is crucially involved in tumor-induced immunosuppression.

Argininosuccinate synthetase catalyzes the transformation of citrulline and aspartate into argininosuccinate and pyrophosphate using the hydrolysis of ATP to AMP and pyrophosphate. This enzymatic process constitutes the rate-limiting step in both the urea and arginine-citrulline cycles. Previous studies have investigated
