ECE‑2 in Human Brain. ECE-2 was detected in immersion fixed paraffin-embedded sections of human brain (cortex) using 3 µg/mL Rat Anti-Human ECE-2 Monoclonal Antibody (Catalog # MAB16451) overnight at 4 °C. Tissue was stained with the Anti-Rat HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS017) and counterstained with hematoxylin (blue).

Background: ECE-2

ECE-2 is a zinc protease of the neprilysin (NEP) family, which also includes ECE-1, PEX, XCE, DINE, Kell and several NEP-like proteins (1). ECE-2 is a type II transmembrane protein with a short cytoplasmic tail and a large ectodomain. Three alternatively spliced forms differ in their cytoplasmic tail (2). In addition to big endothelin-1, ECE-2 cleaves a variety of bioactive peptides such as bradykinin, neurotensin, angiotensin I, substance P, dynorphin B, proenkephalin-derived peptides such as peptide E, BAM 22 and BAM18, and PEN-LEN, an endogenous inhibitor of prohormone convertase 1 (3). Together with ECE-1, it is also involved in degradation of beta -amyloid peptide (4). The ectodomain of human ECE-2 was expressed with an N-terminal His tag and purified.
