LPS suppresses the formation of autophagosomes without influencing the function of lysosomes. a N9 microglial cells were exposed to 1 μg/mL LPS for 6 h, 12 h, and 24 h. The expressions of SQSTM1, an autophagy substrate, and LAMP2, a lysosome membrane protein, were detected by western blot and quantified (b, c). d Levels of Cathepsin E (CTSE) were determined by western blot in microglial cells treated with LPS for 6 h, 12 h, and 24 h, and quantified (e). f N9 microglial cells were treated with 1 μg/mL LPS for 6 h, 12 h, and 24 h, or with 100 nM bafilomycin A1 for 6 h. The fluorescence intensity of LysoSensor was recorded with a 443-nm excitation filter and a 505-nm emission filter. g N9 microglial cells were treated with LPS in the presence or absence of 10 μμ chloroquine (CQ) for 24 h. The expression of autophagy-related proteins was measured by western blot and quantified (h, i). Data are presented as mean ± SEM. *p < 0.05, **p < 0.01, ***p < 0.001 vs control; #p < 0.05, ##p < 0.01 vs CQ

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.
