External Ids for CTSE Gene
The protein encoded by this gene is a gastric aspartyl protease that functions as a disulfide-linked homodimer. This protease, which is a member of the peptidase C1 family, has a specificity similar to that of pepsin A and cathepsin D. It is an intracellular proteinase that does not appear to be involved in the digestion of dietary protein and is found in highest concentration in the surface of epithelial mucus-producing cells of the stomach. It is the first aspartic proteinase expressed in the fetal stomach and is found in more than half of gastric cancers. It appears, therefore, to be an oncofetal antigen. Transcript variants utilizing alternative polyadenylation signals and two transcript variants encoding different isoforms exist for this gene. [provided by RefSeq, Jul 2008]
GeneCards Summary for CTSE Gene
CTSE (Cathepsin E) is a Protein Coding gene. Diseases associated with CTSE include pancreatic cancer. Among its related pathways are Class I MHC mediated antigen processing and presentation and Lysosome. GO annotations related to this gene include protein homodimerization activity and aspartic-type endopeptidase activity. An important paralog of this gene is BACE1.
UniProtKB/Swiss-Prot for CTSE Gene
May have a role in immune function. Probably involved in the processing of antigenic peptides during MHC class II-mediated antigen presentation. May play a role in activation-induced lymphocyte depletion in the thymus, and in neuronal degeneration and glial cell activation in the brain.
