Invitrogen™ Human Presenilin 1 (aa 304-382) Control Fragment Recombinant Protein

Product Code. 30202924

Brand: Invitrogen™ RP89120

Description

Recombinant Protein

Highest antigen sequence indentity to the following orthologs: Mouse (82%), Rat (82%). This recombinant protein control fragment may be used for blocking experiments. In IHC/ICC and WB experiments, we recommend a 100x molar excess of the protein fragment control based on the concentration and the molecular weight. Pre-incubate the antibody-protein control fragment mixture for 30 min at room temperature.

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.
