Protein

ATP-binding cassette sub-family G member 1

Gene

Abcg1

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Transporter involved in macrophage lipid homeostasis. 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.1 Publication

Expressioni

Tissue specificityi

Expressed mainly in brain, thymus, lung, adrenals, spleen and placenta. Little or no expression in liver, kidney, heart, muscle or testes.

Inductioni

Strongly induced in macrophage cell line RAW 264.7 during cholesterol influx. Induction is mediated by the liver X receptor/retinoid X receptor (LXR/RXR) pathway. Down-regulated by endotoxins or cytokines (TNF and IL1) in J-774 macrophages.1 Publication
