Description

Description

MA1-752 detects presenilin 1 protein (PS1) from mouse, rat, human, and nonhuman primate samples. No cross-reactivity is seen with presenilin 2. MA1-752 has successfully been used in immuno-fluorescence, immunocytochemistry, Western blot, immunoprecipitation, and ELISA procedures. By Western blot, this antibody detects an ~18 kDa protein representing PS1 CT (C-terminus fragment) and the ~46 kDa full-length PS1 from transfected SH-SY5Y cells. In 4% paraformaldehyde fixed N2a cells, MA1-752 showed endogenous PS1 staining in the Golgi and cellular vesicles. The MA1-752 immunogen is a synthetic peptide corresponding to residues C S(313) K Y N A E S T E R E S Q D T V A E N D D G(334) of humen PS1.

Presenilin1 was initially identified a marker of susceptibility to early-onset Alzheimer's disease. In addition to PEN2, nicastrin and APH-1, Presenilin1 forms the -gamma-secretase protein complex, a membrane-bound aspartyl protease that can cleave certain proteins at peptide bonds buried within the hydrophobic environment of the lipid bilayer. This cleavage is responsible for a key step in signaling from several cell-surface receptors and is thought to be required for the generation of the neurotoxic amyloid peptides that are central to the pathogenesis of Alzheimer's disease. Like the tumor necrosis factor-alpha-converting enzyme (TACE) and the beta-site cleavage enzyme (BACE) protease families, -gamma-secretase will cleave the amyloid precursor protein (APP), but within the intramembrane region of APP, resulting in either the non-toxic p3 (from the alpha and -gamma cleavage site) or the toxic Abeta amyloid peptide (from the beta and -gamma cleavage site). It is thought that accumulation of the Abeta peptide is the precursor to Alzheimer's disease. Multiple isoforms of presenilin1 are known to exist.
