Figure 6.
R306K-MCT1 is expressed at the plasma membrane of Xenopus oocytes but is inactive. Details are as given for Figure 4. Transport measurements are not shown because R306K-MCT1 failed to elicit any lactate transport whether or not WT- or E218R-basigin cRNA was co-injected. This Figure is reproduced in colour in Molecular Membrane Biology online.
