Burckhardt B, Henjakovic M, Hagos Y, Burckhardt G. Counter-flow suggests transport of dantrolene and 5-OH dantrolene by the organic anion transporters 2 (OAT2) and 3 (OAT3). Pflugers Arch. 2016;468:1909-1918 pubmed
Schweikhard E, Kempson S, Ziegler C, Burckhardt B. Mutation of a single threonine in the cytoplasmic NH2 terminus disrupts trafficking of renal betaine-GABA transporter 1 during hypertonic stress. Am J Physiol Renal Physiol. 2014;307:F107-15 pubmed publisher
..T40A, however, cannot be phosphorylated, as revealed using a specific anti-phosphoantibody, and, therefore, T40 may be important for the trafficking and insertion of BGT1 in the plasma membrane. ..

..Efflux of NCG across the luminal membrane into the tubular lumen probably occurs by OAT4 completing renal secretion of this drug. ..

..At OAT1, more than one binding site must be assumed to explain substrate and drug-dependent stimulation and inhibition of transport activity. ..
Henjakovic M, Hagos Y, Krick W, Burckhardt G, Burckhardt B. Human organic anion transporter 2 is distinct from organic anion transporters 1 and 3 with respect to transport function. Am J Physiol Renal Physiol. 2015;309:F843-51 pubmed publisher
..These experiments suggest that OAT2-mediated cGMP uptake does not occur via exchange with monocarboxylates, dicarboxylates, and hydroxyl ions. The counter anion for electroneutral cGMP uptake remains to be identified. ..
