Protein Structure

UniProt Annotation

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. {ECO:0000269PubMed:14668945}.

Subcellular Localization

Membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}.

Disease Associations

Tissue Specificity

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