Gene Information

human ... ASL(435)

General description

ASL (Argininosuccinate lyase) exists in monomeric state with ~52kDa molecular weight. It turns into the homotetrameric functional state after addition of four active sites. It is highly expressed in liver but also found at low extent in kidney, small intestine, pancreas, muscle, brain, heart, and erythroblast.

Biochem/physiol Actions

ASL (Argininosuccinate lyase) plays a vital role in hepatic urea cycle. It stimulates the conversion of argininosuccinate into arginine and fumarate. This hydrolytic separation helps to remove waste nitrogen. It also produces nitric oxide through the arginine-citrulline cycle. Mutation in ASL gene causes an autosomal recessive disorder, argininosuccinic aciduria. Study has been reported that ASL behaves as a prognostic marker in several types of hepatocellular carcinomas (HCC).

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 APREST74654.

Physical form

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide

Argininosuccinate synthase 1 (ASS1) is the rate-limiting enzyme for arginine biosynthesis. ASS1 expression is lost in a range of tumor types, including 50% of malignant pleural mesotheliomas. Starving ASS1-deficient cells of arginine with arginine blockers such as ADI-PEG20 can induce...

Argininosuccinate lyase (ASL) is an important enzyme in the hepatic urea cycle, and catalyzes the reversible reaction of argininosuccinate to arginine and fumarate. Its expression is significantly reduced in some hepatocellular carcinomas (HCC). In this study, we aimed to investigate...

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. Reconstitution of adaptive immune functions in the context of arginase-mediated tumor immune escape is...
