Uptake of hPAT4-mediated [3H]proline in normal (2 mm) and raised (50 mm) extracellular potassium, normalized to that seen in the normal potassium (mean uptake of 25.3 ± 12.2 and 31.8 ± 24.9 fmol/oocyte/h, respectively, n = 3 oocyte preparations with p < 0.05 for 2 mmversus 50 mm for hPAT1 and p > 0.05 for hPAT4 in each).
