Supplementary information

Cathepsin E also known as CATE is an aspartic protease with a molecular mass of approximately 40 kDa. It functions within the cell to perform endopeptidase activity meaning it cleaves peptide bonds within proteins. Cathepsin E shows expression in the gastric mucosa and is prevalent in immune-related tissues such as the spleen and thymus. This enzyme operates optimally at acidic pH levels specializing in the breakdown of proteins in lysosomes.
Biological function summary

Cathepsin E plays a role in protein degradation and processing within lysosomal compartments. It associates with lysosomal and endosomal pathways participating actively in immune response regulation. Cathepsin E does not form part of a larger complex; however its activity can influence the function of other immune-related proteins by modifying antigen presentation.

Pathways

Cathepsin E engages with the major histocompatibility complex (MHC) class II pathway. This involvement assists in the processing of antigenic peptides for presentation to CD4+ T-cells connecting Cathepsin E to adaptive immune responses. Additionally it interacts with proteins such as HLA-DM which modulates the peptide loading on MHC class II molecules during immune surveillance.

Researchers link Cathepsin E to gastric cancer and Alzheimer's disease. In gastric cancer Cathepsin E overexpression can alter tumor microenvironments impacting disease progression. Furthermore in Alzheimer's disease Cathepsin E's activity correlates with amyloid precursor protein (APP) metabolism which can influence the accumulation of amyloid-beta plaques a hallmark of the disease process.

Target data

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.
