KAT1 is a cloned plant potassium channel belonging to the superfamily of Shaker-like Kv channels. Previous studies have shown that 14-3-3 proteins significantly increase KAT1 current by modifying the channel open probability. Employing a 14-3-3 scavenger construct to lower the long-term availability of endogenous 14-3-3 proteins, we found that 14-3-3 proteins not only control the voltage dependency of the channel but also the number of channels in the plasma membrane.
14-3-3 proteins regulate the K+ channel KAT1 by a dual mode.

Abstract
KAT1 is a cloned plant potassium channel belonging to the superfamily of Shaker-like Kv channels. Previous studies have shown that 14-3-3 proteins significantly increase KAT1 current by modifying the channel open probability. Employing a 14-3-3 scavenger construct to lower the long-term availability of endogenous 14-3-3 proteins, we found that 14-3-3 proteins not only control the voltage dependency of the channel but also the number of channels in the plasma membrane.File in questo prodotto:
