Background
Nicastrin protein is an essential subunit of the gamma-secretase complex, an endoprotease assembly pivotal for catalyzing the intramembrane cleavage of integral membrane proteins, including Notch receptors and amyloid-beta precursor protein (APP). Operating in Notch and Wnt signaling cascades, the gamma-secretase complex regulates downstream processes by processing key regulatory proteins and modulating cytosolic CTNNB1 levels. As a fundamental component of the gamma-secretase complex, Nicastrin collaborates with a presenilin homodimer (PSEN1 or PSEN2), APH1 (APH1A or APH1B), and PSENEN/PEN2 to form the functional complex. This intricate molecular machinery binds to proteolytically processed C-terminal fragments C83 and C99 of APP and engages in interactions with PSEN1 and PSEN2, underscoring its significant role in molecular pathways and cellular processes.

Product Properties
Lyophilized powder.
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
<1 EU/μg, determined by LAL method.
It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).
Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
Room temperature in continental US; may vary elsewhere.
