Protein Structure
UniProt Annotation
Function Forms a channel with a broad specificity. Mediates passage of a wide variety of non-charged solutes including carbamides, polyols, purines, and pyrimidines in a phloretin- and mercury-sensitive manner, whereas amino acids, cyclic sugars, Na(+), K(+), Cl(-), and deprotonated monocarboxylates are excluded. Also permeable to urea and glycerol. {ECO:0000269PubMed:10564231}.
Subcellular Localization Membrane; Multi-pass membrane protein.
Disease Associations
Tissue Specificity Highly expressed in peripheral leukocytes. Also expressed in liver, lung, and spleen.
