Nicastrin Protein, Human (HEK293, His)

Nicastrin Protein, a crucial gamma-secretase complex subunit, catalyzes intramembrane cleavage of Notch receptors and APP.Operating in Notch and Wnt signaling, the complex modulates regulatory proteins and CTNNB1 levels.Collaborating with PSEN1/2, APH1A/B, and PSENEN/PEN2, Nicastrin binds to proteolytically processed C83 and C99 fragments, emphasizing its pivotal role in molecular pathways and cellular processes.Nicastrin Protein, Human (HEK293, His) is the recombinant human-derived Nicastrin protein, expressed by HEK293 , with C-His labeled tag.

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.

  Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.2 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. 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.
