Cryo-EM structures of the ABCA4 importer reveal mechanisms underlying substrate binding and Stargardt disease

Nature Communications, 2021
ABCA4 is an ATP-binding cassette (ABC) transporter that flips N-retinylidenephosphatidylethanolamine (N-Ret-PE) to the cytoplasmic leaflet of photoreceptor membranes. ABCA4 mutations are associated with loss of vision.

Boosted coupling of ATP hydrolysis to substrate transport upon cooperative estradiol-17-beta-D-glucuronide binding in a Drosophila ATP binding cassette type-C transporter [PDF]

, 2018
ATP binding cassette type-C (ABCC) transporters move molecules across cell membranes upon hydrolysis of ATP; however, their coupling of ATP hydrolysis to substrate transport remains elusive.

Thematic Review Series: Lipid Transfer Proteins ABCG5 and ABCG8: more than a defense against xenosterols

Journal of Lipid Research, 2018
The elucidation of the molecular basis of the rare disease, sitosterolemia, has revolutionized our mechanistic understanding of how dietary sterols are excreted and how cholesterol is eliminated from the body.

ATP-binding cassette transporter A1: From metabolism to neurodegeneration

Neurobiology of Disease, 2014
ATP-binding cassette transporter A1 (ABCA1) mediates cholesterol efflux to lipid-free apolipoprotein A-I (apoA-I) and apolipoprotein E (apoE). ABCA1 is an essential regulator of high density lipoproteins (HDL) and reverse cholesterol transport — a role ...

ATP-Binding Cassette Transporters, Atherosclerosis, and Inflammation [PDF]

Circulation Research, 2014
Although recent genome-wide association studies have called into question the causal relationship between high-density lipoprotein (HDL) cholesterol levels and cardiovascular disease, ongoing research in animals and cells has produced increasing evidence that cholesterol efflux pathways mediated by ATP-binding cassette (ABC) transporters and HDL ...

Stanol esters decrease plasma cholesterol independently of intestinal ABC sterol transporters and Niemann-Pick C1-like 1 protein gene expression

Journal of Lipid Research, 2004
Possible mechanisms for the cholesterol-lowering effects of plant stanol esters were addressed by feeding hamsters diets containing stanol esters, cholesterol, or cholestyramine/lovastatin.

Phosphorylation is required for the pathogen defense function of the Arabidopsis PEN3 ABC transporter. [PDF]

, 2017
The Arabidopsis PEN3 ABC transporter accumulates at sites of pathogen detection, where it is involved in defense against a number of pathogens. Perception of PAMPs by pattern recognition receptors initiates recruitment of PEN3 and also leads to PEN3 ...
