Legumain (UniProt: Q99538; EC:3.4.22.34, also known as Asparaginyl endopeptidase; Protease, cysteine 1) is encoded by LGMN (also known as PRSC1) gene (Gene ID 5641) in human. Legumain is a lysosomal enzyme with strict specificity of the hydrolysis of asparaginyl bonds. It is shown to be ubiquitously distributed with abundance in kidney, heart, and placenta. In the zymogen form, the uncleaved propeptide blocks access to the active site. It is activated autocatlytically by acidic pH and the active form is shown to be monomeric. Legumain plays a pivotal role in the endosomal/lysosomal degradation system and is involved in the processing of bacterial peptides and endogenous proteins for MHC class II presentation. Legumain deficiency causes the accumulation of pro-cathepsins B, H and L. Overexpression of legumain is associated with invasion and metastasis in a majority of solid tumors.
