ABCG1 regulates pulmonary surfactant metabolism in mice and men[S] [PDF]
Idiopathic pulmonary alveolar proteinosis (PAP) is a rare lung disease characterized by accumulation of surfactant. Surfactant synthesis and secretion are restricted to epithelial type 2 (T2) pneumocytes (also called T2 cells). Clearance of surfactant is

SR-BI associates with ABCG1 and inhibits ABCG1-mediated cholesterol efflux from cells to high-density lipoprotein 3 [PDF]
Background The single and combined effects of scavenger receptor-BI (SR-BI), ATP-binding cassette transporter (ABC) A1 and G1 on cholesterol efflux from Chinese Hamster Ovary (CHO) cells were investigated. Results When apolipoproteinA-I (apoA-I) was used

Intracellular Localization of Endogenous Mouse ABCG1 Is Mimicked by Both ABCG1-L550 and ABCG1-P550—Brief Report [PDF]
Objective— In a recent article in Arteriosclerosis, Thrombosis, and Vascular Biology , it was reported that ATP-binding cassette transporter G1 (ABCG1) containing leucine at position 550 (ABCG1-L550) was localized to the plasma membrane, whereas ABCG1-P550 (proline at position 550) was

Inhibition of mitogen-activated protein kinase Erk1/2 promotes protein degradation of ATP binding cassette transporters A1 and G1 in CHO and HuH7 cells. [PDF]
Signal transduction modulates expression and activity of cholesterol transporters. We recently demonstrated that the Ras/mitogen-activated protein kinase (MAPK) signaling cascade regulates protein stability of Scavenger Receptor BI (SR-BI) through ...

ABCG1: How critical for cholesterol transport? [PDF]
In the current issue of Cell Metabolism, Kennedy et al. (2005) have extended our understanding of the ABCG1 transporter. Their studies demonstrate that, at least in macrophages, ABCG1 is responsible for much of the cholesterol efflux that utilizes mature HDL as an acceptor.

Structure and Function Studies of ABCG1 [PDF]
ATP-binding cassette transporter G1 (ABCG1) mediates sterol efflux onto lipidated lipoproteins and plays an important role in macrophage cholesterol homeostasis. In this project, we investigated how ABCG1 works as a functional transporter to mediate sterol translocation.

Adrenal Abcg1 Controls Cholesterol Flux and Steroidogenesis [PDF]
Abstract Cholesterol is the precursor of all steroids, but how cholesterol flux is controlled in steroidogenic tissues is poorly understood. The cholesterol exporter ABCG1 is an essential component of the reverse cholesterol pathway and its global inactivation results in neutral lipid redistribution to tissue macrophages. The function of

Efflux of sphingomyelin, cholesterol, and phosphatidylcholine by ABCG1 [PDF]
Cholesterol and phospholipids are essential to the body, but an excess of cholesterol or lipids is toxic and a risk factor for arteriosclerosis. ABCG1, one of the half-type ABC proteins, is thought to be involved in cholesterol homeostasis.

Functional Cooperativity between ABCG4 and ABCG1 Isoforms [PDF]
ABCG4 belongs to the ABCG subfamily, the members of which are half transporters composed of a single transmembrane and a single nucleotide-binding domain. ABCG proteins have a reverse domain topology as compared to other mammalian ABC transporters, and have to form functional dimers, since the catalytic sites for ATP binding and hydrolysis, as well as ...

Resveratrol modulates ATPase activity of liposome‐reconstituted ABCG1 [PDF]
ABCG1 is a half‐sized transporter with an unquestionable importance in cholesterol homeostasis. So far, its expression and thus its activity was suggested to be regulated at transcriptional level by LXR and PPAR agonists including polyphenols. However, it is unknown whether there are other mechanisms of up‐regulation of ABCG1 activity.
