Fusicoccin Activates KAT1 Channels by Stabilizing Their Interaction with 14-3-3 Proteins.
Plants acquire potassium (K+) ions for cell growth and movement via regulated diffusion through K+ channels. Here, we present crystallographic and functional data showing that the K+ inward rectifier KAT1 (K+Arabidopsis thaliana 1) channel is regulated by 14-3-3 proteins and further modulated by the phytotoxin fusicoccin, in analogy to the H+-ATPase. We identified a 14-3-3 mode III binding site...
متن کاملInteraction of phosphorylated tryptophan hydroxylase with 14-3-3 proteins.
Rabbit brain tryptophan hydroxylase (TPH) has been expressed in insect cells (Spodoptera frugiperda) as a histidine-tagged enzyme. The specific activity of the purified fusion enzyme is 80 nmol of 5-hydroxytryptophan/min/mg. Multifunctional regulatory 14-3-3 proteins were purified from fresh bovine brain. Phosphorylation and 14-3-3 proteins play important roles in the regulation of TPH activity...
متن کاملThe phytotoxin fusicoccin promotes platelet aggregation via 14-3-3-glycoprotein Ib-IX-V interaction.
The fungal toxin fusicoccin induces plant wilting by affecting ion transport across the plasma membrane of plant cell. The activity of this toxin is so far unknown in humans. In the present study we show that fusicoccin is able to affect the platelet aggregation process. The toxin associates with platelet intracellular binding sites and induces aggregation in platelet-rich plasma in a dose-depe...
متن کاملFusicoccin, 14-3-3 proteins, and defense responses in tomato plants.
Fusicoccin (FC) is a fungal toxin that activates the plant plasma membrane H+-ATPase by binding with 14-3-3 proteins, causing membrane hyperpolarization. Here we report on the effect of FC on a gene-for-gene pathogen-resistance response and show that FC application induces the expression of several genes involved in plant responses to pathogens. Ten members of the FC-binding 14-3-3 protein gene...
متن کاملPlant 14-3-3 proteins assist ion channels and pumps.
Turgor pressure is a cellular parameter, important for a range of physiological processes in plants, like cell elongation, gas exchange and gravitropic/phototropic bending. Regulation of turgor pressure involves ion and water transport at the expense of metabolic energy (ATP). The primary pump in the plasma membrane (the H(+)-ATPase) is a key player in turgor regulation since it provides the dr...
