“…Besides triggering C-type inactivation, we show that in Shaker and Kv1.2 channels (expressed in Xenopus laevis oocytes), prolonged membrane depolarizations also slow down the kinetics of VSD deactivation and BC gate closure during the subsequent membrane repolarization. …”

“…Single-channel currents were monitored in inside-out patches made from Xenopus laevis oocytes expressing the channels. With 110 mM K(+) in the inside (cytoplasmic) solution and 11 mM K(+) in the outside (extracellular) solution, these three cations blocked K(+) currents with a range of apparent affinities (K(i) (0) = 1.6 mM for Mg(2+), 160 mM for Na(+), and 1.8 mM for TEA(+)) but with similar voltage dependence (zδ = 0.58 for Mg(2+), 0.71 for Na(+), and 0.61 for TEA(+)) despite having different valences. …”

“…The purpose of the present study was to analyze (1) the expression patterns of PACRG during vertebrate embryogenesis, and (2) whether the PACRG protein was required for left-right (LR) axis specification through cilia-driven leftward flow in Xenopus laevis. METHODS: PACRG cDNAs were cloned and expression was analyzed during early embryonic development of Xenopus, mouse, rabbit and zebrafish. …”

“…Here, we report the effects of this compound on members of the TREK (TWIK related K(+) channels) subfamily of human KCNK channels. We injected Xenopus laevis oocytes with cRNAs (complementary RNAs) encoding several KCNK channels and measured their response using the two-electrode voltage clamp technique. 2-APB was found to be an effective activator for all members of the TREK subfamily (hKCNK2, hKCNK4, and hKCNK10), with the highest efficacy in hKCNK10. …”
