KDC1, a carrot Shaker-like potassium channel, reveals its role as a silent regulatory subunit when expressed in plant cells
The Shaker potassium channels are tetrameric proteins formed by the assembly of four α-subunits. The oligomerization can occur among both homo- and hetero-α-subunits. KDC1 is a carrot Shaker-like potassium cha...

A Novel K+ Channel Expressed in Carrot Roots with a Low Susceptibility Toward Metal Ions
Kdc1 is a novel K+-channel gene cloned from carrot roots, and which is also present in cultured carrot cells. We investigated the characteristics of the ionic current elicited in Xenopus oocytes coinjected with K...

Effects of mono- and multi-valent cations on the inward-rectifying potassium channel in isolated protoplasts from maize roots
Transport properties mediated by ionic channels were studied by the patch-clamp technique in protoplasts from cortical parenchyma cells of maize roots (CPMR). While outward currents could be seen only occasio...

Bacterial hemolysins and leukotoxins affect target cells by forming large exogenous pores into their plasma membrane.Escherichia coli hemolysin a as a case example
Many bacteria include among their virulence factors exoproteins which exert leukocidal and cytolytic functions and have the ability to form pores in model membranes. We show that, at least in the case of the R...

The voltage-dependent potassium-uptake channel of corn coleoptiles has permeation properties different from other K+ channels
The initial response of coleoptile cells to growth hormones and light is a rapid change in plasma-membrane polarization. We have isolated protoplasts from the cortex of maize (Zea mays L.) coleoptiles to study th...
