Mouse Proprotein Convertase 9 / PCSK9 ELISA Standard Curve
Preparation and Storage
Background: Proprotein Convertase 9/PCSK9
PCSK9 (proprotein convertase subtilisin kexin 9), also called proprotein convertase 9 or NARC-1 (neural apoptosis-regulated convertase 1), is a member of the proteinase K subfamily of subtilisinrelated serine endoproteases. Mouse PCSK9 cDNA encodes 694 amino acids, including a signal peptide, a prodomain, and a catalytic domain. PCSK9 is highly expressed in the liver, intestine, and kidney. It is initially synthesized as a soluble 74 kDa precursor protein. In the endoplasmic reticulum, it undergoes autocatalytic intramolecular cleavage to generate a 14 kDa prodomain and a 60 kDa catalytic domain. While within the secretion pathway, the prodomain remains associated and functions as a chaperone for the catalytic domain (1-4). During secretion, a portion of active PCSK9 may undergo additional N-terminal proteolysis by furin or proprotein convertase 5/6A, creating an inactive 53 kDa form (5). This cleavage site is conserved between mouse and human or rat PCSK9, which share 78% or 93% amino acid sequence identity, respectively. While the 60 kDa protein is the major form, its ratio with the 53 kDa forms is variable in humans (5, 6).
