Gene Name 44836
Uniprot ID S22A2_HUMAN
KEGG Pathway hsa:6582
Protein Family Major facilitator (TC 2.A.1) superfamily
Protein Function
Mediates tubular uptake of organic compounds from circulation. Mediates the influx of agmatine, dopamine, noradrenaline (norepinephrine), serotonin, choline, famotidine, ranitidine, histamine, creatinine, amantadine, memantine, acriflavine, 4-[4-(dimethylamino)-styryl]-N-methylpyridinium ASP, amiloride, metformin, N-1-methylnicotinamide (NMN), tetraethylammonium (TEA), 1-methyl-4-phenylpyridinium (MPP), cimetidine, cisplatin and oxaliplatin. Cisplatin may develop a nephrotoxic action. Transport of creatinine is inhibited by fluoroquinolones such as DX-619 and LVFX. This transporter is a major determinant of the anticancer activity of oxaliplatin and may contribute to antitumor specificity.

      Mechanism Description
  • Decreased clearance of Dofetilide due to the transporter inhibition by Erdafitinib 

Recommended Action
      Management Concomitant use of erdafitinib and OCT2 substrates should generally be avoided or the dose of the OCT2 substrates should be reduced based on tolerability.
