Human Cathepsin E Antibody Summary

Species Reactivity
Human
Specificity
Detects human pro and active Cathepsin E in direct ELISAs and Western blots. In direct ELISAs and Western blots, approximately 40% cross‑reactivity with recombinant mouse Cathepsin E is observed and less than 2% cross‑reactivity with recombinant human (rh) Cathepsin D and rhBACE is observed.

Background: Cathepsin E

Cathepsin E is an intracellular aspartic protease of the pepsin family (1). Unlike Cathepsin D, another member of the same family and a lysosomal protease with relatively ubiquitous distribution, Cathepsin E is not a lysosomal enzyme and has a limited cell and tissue distribution. However, both Cathepsin D and E play an important role in the degradation of proteins, the generation of bioactive proteins, and antigen processing (2). Both enzymes are efficient in cleaving Swedish mutant of amyloid precursor protein (APP) at the beta  site but show almost no reactivity with wild-type APP (3). Human Cathepsin E is synthesized as a precursor protein, consisting of a signal peptide (residues 1‑17), a propeptide (residues 18‑53), and a mature chain (residues 54‑396) (4).
