GPIHBP1 (Glycosylphosphatidylinositol-anchored high density lipoprotein-binding protein 1) is a glycosyl-phosphatidylinositol (GPI)-linked cell surface glycoprotein. A variety of GPI-linked surface glycoproteins are composed of one or more copies of a conserved domain of ~100 amino-acid residues termed u-PAR/Ly-6 motif that was originally found in u-PAR (Urokinase plasminogen activator surface receptor) and Ly-6/CD59.  The u-PAR/Ly-6 motif has 10 conserved cysteines with a defined disulfide-bonding pattern. GPIHBP1 contains 1 copy of  u-PAR/Ly6 motifs in the extracellular domain (ECD).  GPIHBP1 is a capillary endothelial cell protein that facilitates the lipolytic processing of triglyceride-rich lipoproteins.  GPIHBP1 plays a key role in the lipolytic processing of chylomicrons and is required for the transport of lipoprotein lipase (LPL) into the capillary lumen. Mutations in the GPIHBP1 gene are the cause of hyperlipoproteinemia type 1D (HLPP1D), which is an autosomal recessive disorder characterized by hyperlipoproteinemia, decreased plasma LPL levels in some patients, high plasma triglyceride levels, and refractory fasting chylomicronemia.

Product Details

 

Gene Symbol: GPIHBP1; HBP1; HYPL1D; HLPP1D; GPI-HBP1

 

NCBI Gene ID: 338328

 

Uniprot Entry: Q8IV16

 

Construct Details: Full length human GPIHBP1 gene is subcloned into the Lentiviral expression vector pLTC with an upstream CMV promoter and with or without a selection marker, which can be used for both transient and stable expression in mammalian cells.  It can be co-transfected with the LentiPAK DNA mix (SKU# LP-001) into HEK293 cells to produce high titer lentiviral particles. Multiple choices of a stable antibiotic selection marker are available.

 

Vector Type: pLTC or pLTC-IRES-Marker (lentiviral expression vector containing a heterologous CMV promoter +/- a selection marker, see the vector map above)

 

Formulation: Supplied with 10 μg of endotoxin-free plasmid DNA at 200 ng/μl in sterile TE buffer (pH8.0)

 

Gene Insert Size: 555 (bp)

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
