PCSK9 Protein, Human (Biotinylated, V474I, G670E, HEK293, Avi)

Customer Review

Based on 1 Customer Validation

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, Human (Biotinylated, V474I, G670E, HEK293, Avi) is the recombinant human-derived PCSK9 protein, expressed by HEK293 , with C-Avi labeled tag and V474I, G670E mutation.

Biological Activity

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, Human (Biotinylated, V474I, G670E, HEK293, Avi) is the recombinant human-derived PCSK9 protein, expressed by HEK293 , with C-Avi labeled tag and V474I, G670E mutation.

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.
