Notch3 Protein, Human (HEK293, Fc)

Notch 3 protein is a receptor for the ligands JAG1, JAG2 and DLL1 and plays a crucial regulatory role in cell fate determination. Upon ligand activation, NICD forms a transcriptional activator complex with RBPJ/RBPSUH and activates genes within the enhancer of the cleavage site. Notch3 Protein, Human (HEK293, Fc) is the recombinant human-derived Notch3 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of Notch3 Protein, Human (HEK293, Fc) is 428 a.a., with molecular weight of 75-83 kDa.

Notch 3 protein serves as a receptor for membrane-bound ligands, including Jagged1, Jagged2, and Delta1, playing a pivotal role in regulating cell-fate determination. Upon ligand activation, the released notch intracellular domain (NICD) forms a transcriptional activator complex with RBPJ/RBPSUH, initiating the activation of genes within the enhancer of split locus. This multifaceted protein influences cellular differentiation, proliferation, and apoptotic programs. Structurally, it exists as a heterodimer composed of a C-terminal fragment (N(TM)) and a N-terminal fragment (N(EC)), likely linked by disulfide bonds. Notch 3 interacts with transcriptional coactivators MAML1, MAML2, and MAML3, modulating downstream transcriptional processes. It also engages with PSMA1 and HIF1AN, contributing to diverse cellular functions and regulatory pathways.

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.
