HRP-1392 Recombinant Human LGMN Protein $300

Recombinant Human LGMN Protein

Product Name: Recombinant Human LGMN Protein
Catalog #:  HRP-1392
Manufacture:  LD Biopharma, Inc.

Human legumain preproprotein (LGMN) gene encodes a cysteine protease that has a strict specificity for hydrolysis of asparaginyl bonds. This enzyme may be involved in the processing of bacterial peptides and endogenous proteins for MHC class II presentation in the lysosomal/endosomal systems. Enzyme activation is triggered by acidic pH and appears to be autocatalytic. Protein expression occurs after monocytes differentiate into dendritic cells. A fully mature, active enzyme is produced following lipopolysaccharide expression in mature dendritic cells. Overexpression of this gene may be associated with the majority of solid tumor types. Recent data also indicated that activities of LGMN in brain is involved in the regulating of Tau hyperphophorylation in Alzheimer disease.

Full-length mature human LGMN (416aa) gene was constructed with 29 aa N-terminal T7-His-TEV cleavage tag and expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
