Gene Information

human ... LGMN(5641)

General description

LGMN (legumain) is a cysteine lysosomal endoprotease that cleaves substrates at specific aspartate or asparagine residues. It is predominantly expressed in placenta and kidney, and is also found in brain, heart, liver, spleen and testis. It has a caspase-like fold, with a central six-stranded β-sheet (β1–β6), flanked by five major α-helices (α1–α5). The active form is a monomer. The enzyme is activated autocatalytically by acidic pH. The gene is localized to chromosome 14q32.1.

Legumain precursor recombinant protein epitope signature tag (PrEST)

Western Blotting (1 paper)

Biochem/physiol Actions

LGMN (Legumain) gene encodes a cysteine protease that specifically catalyzes the hydrolysis of asparaginyl bonds. It is involved in the processing of proteins (bacterial and endogenous) for MHC class II presentation in the lysosomal/endosomal systems. Overexpression of legumain has been observed in several solid tumors. It serves as a prognostic marker and a potential therapeutic target is certain cancers, such as gastric carcinoma.

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.
