Specificity / Sensitivity
PEN2 Antibody detects endogenous levels of total PEN2 protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Lys11 of human PEN2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Presenilin Enhancer 2 (PEN2) is a small integral membrane glycoprotein that contains two recognized transmembrane domains. Both the N- and C-terminal domains are oriented into the lumen of the endoplasmic reticulum (1). PEN2, along with Presenilin 1, Presenilin 2, Nicastrin, and APH-1 form the protein complex γ-secretase (2). The proteinase BACE catalyses the initial step in APP processing by cleaving and releasing soluble APPβ (3). The remaining membrane bound APP is then cleaved by the γ-secretase complex, causing the release of amyloid β-peptide, the main constituent of amyloid plaques. These plaques are a hallmark of Alzheimer’s disease pathology (2). In addition to APP, the γ-secretase complex cleaves several other proteins and necessary presenilin-dependent signaling cascades, including the Notch pathway (4). It was found that PEN2 is an important part of the γ-secretase complex, and knocking it down results in reduced amounts of the complex, resulting in a loss of γ-secretase activity (5).
