Target Background

Catalyzes the efflux of phospholipids such as sphingomyelin, cholesterol and its oxygenated derivatives like 7beta-hydroxycholesterol and this transport is coupled to hydrolysis of ATP. The lipid efflux is ALB-dependent. Is an active component of the macrophage lipid export complex. Could also be involved in intracellular lipid transport processes. The role in cellular lipid homeostasis may not be limited to macrophages. Prevents cell death by transporting cytotoxic 7beta-hydroxycholesterol.
Gene References into Functions
  1. HSP70 promotes the progression of atherosclerosis in apoE-/- mice by suppressing the expression of ABCA1 and ABCG1 through the JNK/Elk-1 pathway. PMID: 29678642
  2. TMP upregulated the protein stability of ABCA1 without affecting ABCG1. Accordingly, TMP regulated the expression of SR-A, CD36, ABCA1 and ABCG1 in aortas of ApoE-/- mice, which resembled the findings observed in macrophages. PMID: 28791414
  3. ABCG1 regulates pulmonary surfactant metabolism PMID: 28264879
  4. ABCG1 regulates T cell differentiation into Tregs, highlighting a pathway by which cholesterol accumulation can influence T cell homeostasis in atherosclerosis PMID: 27482882
  5. Our data indicate that a combination of vildagliptin and pravastatin significantly induces the expression of LXR-ABCA1/ABCG1 cascade and improves cholesterol efflux (P > 0.05) in adipocytes. Our data may explain, at least in part, the improvement in HDL-C levels observed in patients receiving both medications PMID: 27251372
  6. ABCG1 may play a protective role in early-stage atherosclerosis by reducing endothelial activation induced by oscillatory shear stress via suppressing the inflammatory response. PMID: 27297110
  7. Endothelial cholesterol efflux pathways mediated by ABCA1 and ABCG1 are nonredundant and atheroprotective, reflecting preservation of endothelial NO synthase activity and suppression of endothelial inflammation, especially in regions of disturbed arterial blood flow. PMID: 27199450
  8. ABCG1, irrespective of either a leucine or proline at position 550, is an intracellular protein that localizes to vesicles of the endosomal pathway where it functions to mobilize sterols away from the endoplasmic reticulum and out of the cell. PMID: 27230131
  9. our study suggests that MEK1/2 inhibitors activate macrophage ABCG1 expression/RCT, and inhibit foam cell formation and lesion development by multiple mechanisms, supporting the concept that ERK1/2 inhibition is anti-atherogenic PMID: 27365310
  10. miR-33 augments macrophage lipid rafts and enhances proinflammatory cytokine induction and NF-kappaB activation by LPS.

  11. ABCG1 expression was down-regulated by TLR4, which induces inflammation and lipid accumulation in vascular smooth muscle cells via PPARgamma/LXRalpha signaling. PMID: 27807703
  12. Visfatin upregulated CD36 and SRA expression and downregulated ABCA1 and ABCG1 expression, subsequently increased ox-LDL uptake and decreased cholesterol efflux, and finally promoted foam cell formation via the PI3K- and ERK-dependent pathways. PMID: 26536203
  13. Leu at position 550/562 in mABCG1/hABCG1 is critical for their plasma membrane localization but not for ABCG1-mediated cholesterol efflux. PMID: 26695502
