Target Background Presenilin 1 (PS1) and presenilin 2 (PS2) are catalytic subunits of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (beta-amyloid precursor protein).The other members of the gamma-secretase complex are required to have protease activity.PS1 and PS2 may play a role in intracellular signaling and gene expression or in linking chromatin to the nuclear membrane.It regulates epithelial-cadherin function.Three causative genes have been identified that when mutated lead to presenile Alzheimer's disease: APP (amyloid precursor protein gene), PSEN1, and PSEN2.The presenilin 1 gene has recently been discovered on chromosome 14 and is responsible for an early onset form of Alzheimer's disease that accounts for 70-80% of the inherited forms of Alzheimer's.It is a membrane protein that has a region where at least seven mutations have been identified in family members with Alzheimer's disease.Endogenous presenilin mainly exists in a heterodimeric complex formed from the endoproteolytically processed amino-terminal (28 kD) and carboxy-terminal (≈17 kD) fragments.GenScript Rabbit Anti-Presenilin 1 Polyclonal Antibody is developed in rabbit hosts using a synthetic peptide, TVRSQNDNRERQEHNDRRSLGHPEPL, corresponding to amino acids 25-50 of the N-terminus of human presenilin 1.Rabbit Anti-Presenilin 1 Polyclonal Antibody is highly purified from rabbit antiserum by immunoaffinity chromatography and is supplied as a 40 μg aliquot at a concentration of 0.5 mg/ml.
