Description

The production of this Recombinant Mouse Apoe protein required the insertion of a DNA fragment (Apoe, 19-311aa) into a plasmid vector and the transferral of this vector into Yeast cells (the step of transformation). The cells were then cultured and induced to express the Apoe protein. This recombinant protein was fused with N-terminal 6xHis tag. Its purity is 90%+ determined by SDS-PAGE.

Apoe is a gene providing an instruction of making a protein named apolipoprotein E (Apo-E) in mus musculus (mouse). This gene has many orthologs in multiple mammals, such as human, norway rat, pig, cattle, etc. Apo-E protein belongs to a family of fat-binding proteins called apolipoproteins, which combines with fats (lipids) in the body to form molecules called lipoproteins. Increasing studies has demonstrated that apoE-deficient mice exhibit neuronal abnormalities similar to those in Alzheimer's disease and enhanced sensitivity to stroke-associated injuries.

Target Background

Function

APOE is an apolipoprotein, a protein associating with lipid particles, that mainly functions in lipoprotein-mediated lipid transport between organs via the plasma and interstitial fluids. APOE is a core component of plasma lipoproteins and is involved in their production, conversion and clearance. Apoliproteins are amphipathic molecules that interact both with lipids of the lipoprotein particle core and the aqueous environment of the plasma. As such, APOE associates with chylomicrons, chylomicron remnants, very low density lipoproteins (VLDL) and intermediate density lipoproteins (IDL) but shows a preferential binding to high-density lipoproteins (HDL). It also binds a wide range of cellular receptors including the LDL receptor/LDLR and the very low-density lipoprotein receptor/VLDLR that mediate the cellular uptake of the APOE-containing lipoprotein particles. Finally, APOE has also a heparin-binding activity and binds heparan-sulfate proteoglycans on the surface of cells, a property that supports the capture and the receptor-mediated uptake of APOE-containing lipoproteins by cells.
