Apolipoprotein E structure: insights into function
Abstract
Human apolipoprotein E (apoE) is a member of the family of soluble apolipoproteins. Through its interaction with members of the low-density lipoprotein receptor family, apoE has a key role in lipid transport both in the plasma and in the central nervous system. Its three common structural isoforms differentially affect the risk of developing atherosclerosis and neurodegenerative disorders, including Alzheimer's disease. Because the function of apoE is dictated by its structure, understanding the structural properties of apoE and its isoforms is required both to determine its role in disease and for the development of therapeutic strategies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
