Gene names: SLC22A18, BWR1A, BWSCR1A, HET, IMPT1, ITM, ORCTL2, SLC22A1L, TSSC5
Protein names and data: S22AI_HUMAN, Full=Solute carrier family 22 member 18, Full=Beckwith-Wiedemann syndrome chromosomal region 1 candidate gene A protein;Full=Efflux transporter-like protein;Full=Imprinted multi-membrane-spanning polyspecific transporter-related protein 1;Full=Organic cation transporter-like protein 2;Short=ORCTL-2;Full=Solute carrier family 22 member 1-like;Full=Tumor-suppressing STF cDNA 5 protein;Full=Tumor-suppressing subchromosomal transferable fragment candidate gene 5 protein;Full=p45-Beckwith-Wiedemann region 1 A;Short=p45-BWR1A; Length: 424 a.a., Mass: 44846 Da,
fasta formatted sequence

Function: May act as a transporter of organic cations based on a proton efflux antiport mechanism. May play a role in the transport of chloroquine and quinidine-related compounds in kidney
Cellular location: Apical cell membrane; Multi-pass membrane protein (Potential). Note=Localized at the apical membrane surface of renal proximal tubules
Tissue specificity: Expressed at high levels in adult and fetal kidney and liver, and adult colon. Expressed in fetal renal proximal tubules (at protein level). Expressed at lower levels in heart, brain and lung
