Description
Biotinylated Human PCSK9 (D374Y) Protein, Avitag™, His Tag | PCY-H82E7-200ug| Gentaur Distribution US, UK & Europe
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is also known as NARC1 (neural apoptosis regulated convertase), is a newly identified subtilase belonging to the peptidase S8 subfamily. Mouse PCSK9 is synthesized as a soluble zymogen, and undergoes autocatalytic intramolecular processing in the endoplasmic reticulum, resulting in the cleavage of its propeptide that remains associated with the secreted active enzyme with a broad alkaline pH optimum. This protein plays a major regulatory role in cholesterol homeostasis. PCSK9 binds to the epidermal growth factor-like repeat A (EGF-A) domain of the low-density lipoprotein receptor (LDLR), inducing LDLR degradation. PCSK9 may also have a role in the differentiation of cortical neurons. Mutations in this gene have been associated with a rare form of autosomal dominant familial hypercholesterolemia (HCHOLA3).
Source: MABSol® Biotinylated Human PCSK9 (D374Y), Avitag, His Tag (PCY-H82E7) is expressed from human HEK293 cells. It contains AA Gln 31 - Gln 692 (Accession # Q8NBP7-1 (D374Y) ).
Format: Powder.
Tag: C-Avi & C-6×His.
Expression System: HEK293.
Expression Region: Gln 31 - Gln 692.
Conjugate: Biotin-labeled.
Molecular Weight: 13.8 kDa and 59.9 kDa.
Characteristics: This protein carries an Avi tag (Avitag™) at the C-terminus, followed by a polyhistidine tag. This protein undergoes autocatalytic cleavage to release the pro-peptide and mature chain. The pro-peptide and mature chain are associated through non‑covalent interactions and with a calculated MW of 13.8 kDa and 59.9 kDa respectively. The protein migrates as 17 kDa and 60-65 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation. The D374Y mutation results in higher affinity of PCSK9 for LDLR.
Purity: 95%.
Buffer: PBS, pH7.4.
Storage Conditions: -20℃.
Shipping Conditions: RT
