LGMN - legumain Gene

Also Known as AEP; LGMN1; PRSC1

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 5641

About LGMN

Cytogenetic location: 14q32.12 Genomic coordinates (GRCh38): 14:92,703,809-92,748,627 (from NCBI)

This gene has 19 transcripts (splice variants), 210 orthologues and 1 paralogue. Ubiquitous expression in placenta (RPKM 135.7), spleen (RPKM 98.7) and 23 other tissues.

Summary

This 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. This gene has a pseudogene on chromosome 13. Several alternatively spliced transcript variants have been described, but the biological validity of only two has been determined. These two variants encode the same isoform. [provided by RefSeq, Jul 2008]
