General annotation (Comments)

Function	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. Ref.9 Ref.10
Subunit structure	May form heterodimers with several heterologous partners of the ABCG subfamily.
Subcellular location	Endoplasmic reticulum membrane; Multi-pass membrane protein. Golgi apparatus membrane; Multi-pass membrane protein. Note: Predominantly localized in the intracellular compartments mainly associated with the endoplasmic reticulum (ER) and Golgi membranes.
Tissue specificity	Expressed in several tissues. Expressed in macrophages; expression is increased in macrophages from pateints with Tangier disease. Ref.13
Induction	Strongly induced in monocyte-derived macrophages during cholesterol influx. Conversely, mRNA and protein expression are suppressed by lipid efflux. Induction is mediated by the liver X receptor/retinoid X receptor (LXR/RXR) pathway. Not induced by bacterial lipopolysaccharides (LPS). Repressed by ZNF202. Ref.9 Ref.10 Ref.11
Sequence similarities	Belongs to the ABC transporter superfamily. ABCG family. Eye pigment precursor importer (TC 3.A.1.204) subfamily. [View classification] Contains 1 ABC transmembrane type-2 domain. Contains 1 ABC transporter domain.
