Apolipoprotein E structural requirements for the formation of SDS-stable complexes with β-amyloid-(1–40): the role of salt bridges

Abstract excerpt

Of the three major isoforms of human apolipoprotein E (apoE), apoE4 is a risk factor for the development of Alzheimer's disease. Among possible neurologically relevant differences in the properties of apoE3 and apoE4 is the fact that apoE3 forms an SDS-stable complex with beta-amyloid-(1-40) (Abeta40) with greater avidity than does apoE4. This interaction may sequester potentially toxic species of Abeta or...
