|PSENEN in Human Brain. PSENEN was detected in immersion fixed paraffin-embedded sections of human Alzheimer's brain using Mouse Anti‑Human PSENEN Monoclonal Antibody (Catalog # MAB6859) at 15 µg/mL overnight at 4 °C. Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using Antigen Retrieval Reagent-Basic (Catalog # CTS013). Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm and neurites of neurons. View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections.|
Gamma-secretase subunit PSENEN, also called PEN-2 (Presenilin enhancer protein 2) is a 10 kDa member of the PEN-2 family. Human PSENEN is 101 amino acids (aa) in length, and is a multi-pass transmembrane protein. Residues 1-17 are on the luminal side of the endoplasmic reticulum or Golgi apparatus, where PSENEN is primarily located. Amino acids 18-38 form a transmembrane region, and aa 39-60 form a cytoplasmic segment. Another transmembrane segment is formed by residues 61-81, and residues 82-101 are located on the luminal side of the ER or cis-Golgi. Human PSENEN shares 96% aa sequence identity with mouse and rat PSENEN. Functionally, PSENEN is an essential subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and beta-amyloid precursor protein.
