PA1-757 detects transfected beta-secretase 1.
PA1-757 has been successfully used in ELISA, ICC/IF, Western blot and immunoprecipitation applications. The molecular weight of BACE1 detected may vary depending on the lysate tested. This may be due to glycosylation differences in various cell lines.
The PA1-757 immunizing peptide (Cat. # PEP-093) is available for use in neutralization and control experiments.
Amyloid beta peptide is the major constituent of amyloid plaques in the brains of individuals afflicted with Alzheimer's disease. This peptide is generated from the beta-amyloid precursor protein (beta APP) in a two-step process. The first step involves cleavage of the extracellular, amino-terminal domain of beta APP. Protein cleavage is performed by an aspartyl protease termed beta-secretase (BACE), of which there are two isoforms, BACE1 and 2. This enzyme is synthesized as a propeptide that must be modified to the mature and active form by the prohormone convertase, furin. Beta APP cleavage by the mature form of BACE results in the cellular secretion of a segment of beta APP and a membrane-bound remnant. This remnant is then processed by another protease termed gamma-secretase. Gamma-secretase cleaves an intra-membrane site in the carboxyl-terminal domain of beta APP, thus generating the amyloid beta peptide. Gamma-secretase is believed to be a multi-subunit complex containing presenilin-1 and 2 as central components. Found associated with the presenilins is the transmembrane glycoprotein nicastrin. Nicastrin has been found to bind to the carboxyl-terminus of beta APP and helps to modulate the production of the amyloid beta peptide.
