The crystal structure of the C-terminal truncated apolipoprotein A-I sheds new light on amyloid formation by the N-terminal fragment.
Apolipoprotein A-I (apoA-I) is the main protein of plasma high-density lipoproteins (HDL, or good cholesterol) that remove excess cell cholesterol and protect against atherosclerosis. In hereditaryExpand

Amyloidogenic mutations in human apolipoprotein A‐I are not necessarily destabilizing – a common mechanism of apolipoprotein A‐I misfolding in familial amyloidosis and atherosclerosis
High‐density lipoproteins and their major protein, apolipoprotein A‐I (apoA‐I), remove excess cellular cholesterol and protect against atherosclerosis. However, in acquired amyloidosis, nonvariantExpand

Folded functional lipid-poor apolipoprotein A-I obtained by heating of high-density lipoproteins: relevance to high-density lipoprotein biogenesis.
HDL (high-density lipoproteins) remove cell cholesterol and protect from atherosclerosis. The major HDL protein is apoA-I (apolipoprotein A-I). Most plasma apoA-I circulates in lipoproteins, yet ~5%Expand

Kinetic stabilization and fusion of apolipoprotein A-2:DMPC disks: comparison with apoA-1 and apoC-1.
Denaturation studies of high-density lipoproteins (HDL) containing human apolipoprotein A-2 (apoA-2) and dimyristoyl phosphatidylcholine indicate kinetic stabilization. Circular dichroism (CD) andExpand

Amyloid-Forming Properties of Human Apolipoproteins: Sequence Analyses and Structural Insights.
Apolipoproteins are protein constituents of lipoproteins that transport cholesterol and fat in circulation and are central to cardiovascular health and disease. Soluble apolipoproteins canExpand

Monitoring protein aggregation during thermal unfolding in circular dichroism experiments
Thermal unfolding monitored by spectroscopy or calorimetry is widely used to determine protein stability. Equilibrium thermodynamic analysis of such unfolding is often hampered by itsExpand

Temperature-dependent β-sheet formation in β-amyloid Aβ1–40 peptide in water: uncoupling β-structure folding from aggregation
To probe the role of temperature in the conversion of soluble Alzheimer's beta-amyloid peptide (Abeta) to insoluble beta-sheet rich aggregates, we analyzed the solution conformation of Abeta(1-40)Expand

Human plasma high-density lipoproteins are stabilized by kinetic factors.
High-density lipoproteins (HDL) are heterogeneous complexes of proteins and lipids that mediate cholesterol removal from the body. Our thermal and chemical denaturation studies of mature sphericalExpand
