Description

General description

Nicastrin (NCSTN) is a type I transmembrane glycoprotein (709 amino acids) that interacts with both presenilin-1 (PS1) and presenilin-2 (PS2). This gene is located on human chromosome 1q23.

Specificity

Rabbit polyclonal anti-Nicastrin recognizes human nicastrin (110 kDa) by immunoblotting. Staining of nicastrin in immunoblotting is specifically inhibited with nicastrin immunizing peptide.

Immunogen

synthetic peptide corresponding to the C-terminus of human nicastrin (amino acids 693-709) conjugated to KLH. The corresponding sequence is identical in mouse.

Application

Anti-Nicastrin antibody produced in rabbit has been used in:

• western blotting
• immunoprecipitation
• co-immunoprecipitation

Biochem/physiol Actions

Nicastrin has a key role in the regulation of presenilin-mediated cleavage of the b-amyloid precursor protein (b-APP) and Notch/GLP-1. Nicastrin binds to the membrane-tethered form of Notch and is essential for the intramembrane cleavage of Notch to generate Notch intracellular domain (NICD), which is involved in intracellular signaling. It has been suggested that nicastrin binds substrates of presenilin/g-secretase complexes or modulates g-secretase activity. Suppression of nicastrin expression in C. elegansembryos induces a subset of notch/glp-1 phenotypes similar to those induced by simultaneous null mutations in both presenilin homologues of C. elegans (sel-12 and hop-1). Thus, increasing evidence indicates that both nicastrin and presenilins are necessary components for the intramembrane proteolysis of proteins such as b-APP and Notch, and implicates a direct role for nicastrin in the pathogenesis of Alzheimer′s disease and in the regulation of Notch signaling in vivo.
