Cathepsin E Antibody (212211) Summary

• Immunogen: Mouse myeloma cell line NS0-derived recombinant human Cathepsin E
  Gln18-Pro396
  Accession # NP_001901
• Specificity: Detects human Cathepsin E in direct ELISAs and Western blots. It recognizes both the pro and mature forms of recombinant human (rh) Cathepsin E. In Western blots, 100% cross‑reactivity with recombinant mouse (rm) Cathepsin E and recombinant human (rh) BACE is observed under reducing conditions. Under non-reducing conditions, less than 1% cross-reactivity with rmCathepsin E and rhBACE-1 is observed. Less than 1% cross-reactivity with rhCathepsin D is observed under both reducing and non-reducing conditions.

Background

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 (aa 1‑17), a propeptide (aa 18‑53), and a mature chain (aa 54‑396) (4).
