Target Details

Target: ApoE3 (Apolipoprotein E3 (ApoE3))

Alternative Name: APOE3

Background: Apolipoprotein E (apoE) is a lipid carrier in both the peripheral and the central nervous systems. Lipid-loaded apoE lipoprotein particles bind to several cell surface receptors to support membrane homeostasis and injury repair in the brain. Considering prevalence and relative risk magnitude, the ε4 allele of the APOE gene is the strongest genetic risk factor for late-onset Alzheimer's disease (AD).

Molecular Weight: 35.3 kDa. Due to glycosylation, the protein migrates to 35-40 kDa based on Tris-Bis PAGE result.

UniProt: P02649-1

Pathways: Regulation of Cell Size, Lipid Metabolism
