製品の詳細

Human Legumain ELISA Kit is designed for the quantitative determination of Legumain in cell culture supernatants, plasma and serum samples.

This assay employs an antibody specific for human Legumain coated on a 96-well plate. Standards and samples are pipetted into the wells and Legumain present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-human Legumain antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Legumain bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

This ELISA kit shows no cross-reactivity with the following cytokines tested: human 2B4 (CD244), ADAM-9, Angiopoietin-2, APRIL, BMP-2, BMP-9, C5a, Cathepsin L, CD200, CD97, Chemerin, DcR3, FABP2, FAP, FGF-19, Galectin-3, HGFR, IFN-alpha / betaR2, IGF-2, IGF-2 R, IL-1 R6 (IL-1 Rrp2), IL-24, IL-33 (IL-1 F11), Kallikrein 14.

補足情報

This supplementary information is collated from multiple sources and compiled automatically.

Legumain also known as asparaginyl endopeptidase is an enzyme that plays a mechanical role as a protease. This enzyme has a molecular mass of approximately 56 kDa and it functions by catalyzing the hydrolysis of asparagine residues. Legumain is expressed in various tissues with higher levels observed in kidneys placenta and liver. Its proteolytic activity is essential for the breakdown of intracellular proteins within lysosomes and endosomal compartments.
Biological function summary

Legumain contributes to protein degradation and antigen processing. It does not operate alone as it is part of larger protein complexes which enhance its stability and function. Through its role in proteolysis legumain influences cellular processes like maturation of endolysosomal enzymes and processing of proenzymes. Additionally it assists in activating other proteases signifying its critical position in maintaining cellular proteostasis.

Pathways

Legumain participates in the regulation of immune responses and cellular homeostasis. It plays a significant role in the lysosomal pathway where it partners with cathepsins to assist in the degradation of proteins. Additionally legumain influences the MHC class II pathway by contributing to the cleavage of invariant chain aiding antigen presentation. Its interaction with cathepsins and the impact on antigen processing indicates its necessity in immune system functionality.

Legumain has been linked to disorders such as cancer and neurodegeneration. In cancer elevated legumain levels correlate with tumor invasiveness and metastasis especially in association with proteins like matrix metalloproteinases. Meanwhile in neurodegenerative conditions its dysregulation may contribute to abnormal protein accumulation and synaptic dysfunction. Understanding legumain's role and interactions can guide therapeutic strategies for these diseases.

ターゲットの情報

Has a strict specificity for hydrolysis of asparaginyl bonds (PubMed : 23776206). Can also cleave aspartyl bonds slowly, especially under acidic conditions (PubMed : 23776206). Involved in the processing of proteins for MHC class II antigen presentation in the lysosomal/endosomal system (PubMed : 9872320). Also involved in MHC class I antigen presentation in cross-presenting dendritic cells by mediating cleavage and maturation of Perforin-2 (MPEG1), thereby promoting antigen translocation in the cytosol (By similarity). Required for normal lysosomal protein degradation in renal proximal tubules (By similarity). Required for normal degradation of internalized EGFR (By similarity). Plays a role in the regulation of cell proliferation via its role in EGFR degradation (By similarity).
