|Presenilin (PS) facilitates gamma-secretase cleavage of the beta-amyloid precursor protein and the intramembraneous cleavage of Notch1 (1). Presenilin (PS) is essential for the gamma-cleavage required for the generation of the C terminus of amyloid beta-protein (Abeta). The discovery that a deficiency of presenilin 1 (PS1) decreases the production of amyloid beta-protein (Abeta) identified the presenilins as important mediators of the gamma-secretase cleavage of beta-amyloid precursor protein (APP). It has been shown that two conserved transmembrane (TM) aspartates in PS1 are critical for Abeta production, providing evidence that PS either functions as a required diaspartyl cofactor for gamma-secretase or is itself gamma-secretase. Presenilin 2 (PS2) shares substantial sequence and possibly functional homology with PS1. It has been shown that the two TM aspartates in PS2 are also critical for gamma-secretase activity, providing further evidence that PS2 is functionally homologous to PS1 (2). PS are found primarily within intracellular membranes, including the endoplasmic reticulum (ER) and the trans-Golgi network as well as the plasma membrane. PS are also expressed in most cell types throughout development (3). |

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Presenilin 1 antibody [EP2000Y]; Immunohistochemical staining of paraffin-embedded human liver, using ab76083, at 1/100-1/250 dilution.
Flow Cytometry-Anti-Presenilin 1 antibody [EP2000Y](ab76083); Overlay histogram showing HepG2 cells stained with ab76083 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody for 30 min at 22°C. The secondary antibody used was DyLight? 488 goat anti-rabbit IgG (H+L) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x10^6 cells) used under the same conditions. Acquisition of >5,000 events was performed.
