背景信息

The PEN2 antibody is a crucial tool in studying the γ-secretase complex, a multisubunit protease integral to Alzheimer’s disease (AD) research. PEN2 (Presenilin Enhancer 2) is one of four core components of γ-secretase, alongside presenilin (PS1/PS2), Nicastrin, and APH-1. This transmembrane protein plays a pivotal role in stabilizing and activating the catalytic subunit PS1. enabling the complex to cleave substrates like amyloid precursor protein (APP). Cleavage of APP generates amyloid-beta (Aβ) peptides, including neurotoxic Aβ42. which aggregates into plaques—a hallmark of AD pathogenesis. Antibodies targeting PEN2 are essential for detecting its expression, localization, and interaction dynamics within the γ-secretase complex. They are widely used in techniques such as Western blotting, immunoprecipitation, and immunofluorescence to investigate PEN2’s role in cellular models and AD-related tissues. Research utilizing PEN2 antibodies has revealed its involvement in γ-secretase assembly, substrate specificity, and regulatory mechanisms, aiding the development of therapies aimed at modulating Aβ production. Additionally, these antibodies help explore PEN2’s potential functions beyond AD, such as in Notch signaling and cancer biology. Species-specific variants (e.g., human, mouse) enable cross-disciplinary studies, while validation for selectivity ensures reliable data. Overall, PEN2 antibodies remain vital for unraveling γ-secretase biology and its implications in neurodegenerative and other diseases.
