human ... APOE(348)

General description

Apolipoprotein E (ApoE) belongs to a group of proteins that bind reversibly with lipoproteins. Significant quantities of ApoE are produced in liver and brain and to some extent in almost every organ. ApoE is an important constituent of all plasma lipoproteins. ApoE exists in three major isoforms; E2, E3, and E4, which differ from one another by a single amino-acid substitution. Compared with E3 and E4, E2 exhibits the lowest receptor binding affinity. E2 allele carriers have significantly lower levels of total cholesterol, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol, as well as increased ApoE levels. The gene encoding this protein is localized on human chromosome 19q13.32.

Immunogen

Peptide with sequence C-VGTSAAPVPSDNH from the C Terminus of the protein sequence according to NP_000032.1.

Biochem/physiol Actions

In addition to facilitating solubilization of lipids, apolipoproteins help to maintain the structural integrity of lipoproteins, serve as ligands for lipoprotein receptors, and regulate the activity of enzymes involved in lipid metabolism. Apolipoprotein E (ApoE) plays an important role in lipid metabolism. It′s interaction with specific ApoE receptor enables uptake of chylomicron remnants by liver cells, which is an essential step during normal lipid metabolism. It also binds with the LDL receptor (Apo B/E). Defects in ApoE are a cause of hyperlipoproteinemia type III.

The exchangeability of apolipoprotein (apo) E between lipoprotein particles such as very low-density lipoprotein (VLDL) and high-density lipoprotein (HDL) is critical for lipoprotein metabolism, but despite its importance, the kinetics and mechanism of apoE-lipoprotein interaction are not known. We have...

Genome-wide association studies (GWAS) have become a major strategy for genetic dissection of human complex diseases. Analysing multiple phenotypes jointly may improve both our ability to detect genetic variants with multiple effects and our understanding of their common features. Allelic...

The common APOE2 gene variant is neuroprotective against Alzheimer's disease (AD) and reduces risk by nearly 50%. However, the mechanisms by which APOE2 confers neuroprotection are largely unknown. Here we showed that ApoE protein abundance in human postmortem cortex follows...
