Notch 3 Protein, Human (HEK293, C-His-Avi)

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. Notch 3 Protein, Human (HEK293, C-His-Avi) is the recombinant human-derived Notch 3 protein, expressed by HEK293 , with C-His labeled tag.

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.

Partial

Approximately 27-30 kDa & 10-12 kDa,based on SDS-PAGE under reducing conditions,due to the glycosylation.

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

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 8% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

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.
