PCSK9 Protein, Hamster (HEK293, His)
The PCSK9 protein is an important regulator of plasma cholesterol homeostasis, affecting LDL receptor family members such as LDLR and VLDLR. It promotes their intracellular degradation and enhances hepatic LDLR degradation through non-proteolytic mechanisms. PCSK9 Protein, Hamster (HEK293, His) is the recombinant PCSK9 protein, expressed by HEK293 , with C-His labeled tag. The total length of PCSK9 Protein, Hamster (HEK293, His) is 662 a.a., with molecular weight of ~18 kDa.
- Species: Others
- Source: HEK293
-
Storage: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.

Description
The PCSK9 protein is an important regulator of plasma cholesterol homeostasis, affecting LDL receptor family members such as LDLR and VLDLR. It promotes their intracellular degradation and enhances hepatic LDLR degradation through non-proteolytic mechanisms. PCSK9 Protein, Hamster (HEK293, His) is the recombinant PCSK9 protein, expressed by HEK293 , with C-His labeled tag. The total length of PCSK9 Protein, Hamster (HEK293, His) is 662 a.a., with molecular weight of ~18 kDa.
Background
PCSK9 protein emerges as a pivotal regulator in the intricate orchestration of plasma cholesterol homeostasis. Demonstrating its influence on low-density lipid receptor family members, including the low-density lipoprotein receptor (LDLR), very low-density lipoprotein receptor (VLDLR), apolipoprotein E receptor (LRP1/APOER), and apolipoprotein receptor 2 (LRP8/APOER2), PCSK9 facilitates their degradation within intracellular acidic compartments. Employing a non-proteolytic mechanism, it enhances the hepatic LDLR degradation through a clathrin LDLRAP1/ARH-mediated pathway, possibly impeding LDLR recycling and directing it toward lysosomal degradation. Moreover, PCSK9 exhibits LDLR-independent inhibition of APOB intracellular degradation via the autophagosome/lysosome pathway and plays a role in the disposal of non-acetylated BACE1 intermediates in the early secretory pathway. Notably, it regulates epithelial Na(+) channel (ENaC)-mediated Na(+) absorption by augmenting ENaC proteasomal degradation, and influences neuronal apoptosis through the modulation of LRP8/APOER2 levels and associated anti-apoptotic signaling 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 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.
