Nicastrin Protein, Mouse (HEK293, His)

Nicastrin is an important subunit of the γ-secretase complex and plays a key role in the endoproteolytic cleavage of integral membrane proteins, including Notch receptors and amyloid-β precursor protein (APP). In the γ-secretase complex, nicastin acts as a key regulator of Notch and Wnt signaling cascades and affects downstream processes. Nicastrin Protein, Mouse (HEK293, His) is the recombinant mouse-derived Nicastrin protein, expressed by HEK293 , with C-His labeled tag.

Nicastrin, an indispensable subunit of the gamma-secretase complex, takes center stage in the intricate molecular machinery responsible for the endoproteolytic cleavage of integral membrane proteins. This includes pivotal substrates like Notch receptors and the amyloid-beta precursor protein (APP). The gamma-secretase complex, in which Nicastrin plays a crucial role, serves as a linchpin in the modulation of Notch and Wnt signaling cascades, exerting regulatory influence on downstream processes. In concert with other essential components, such as a presenilin homodimer, APH1, and PEN2, Nicastrin forms the functional gamma-secretase complex. Nicastrin's binding affinity extends to the proteolytically processed C-terminal fragments of APP, further underscoring its pivotal role in orchestrating the intricacies of this proteolytic machinery. Moreover, Nicastrin's interactions with presenilin components accentuate its integral role within the gamma-secretase complex.

  ≥ 95%, as determined by reducing SDS-PAGE.

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.
