an essential role of the vacuolar potassium channel TPK1 in salt-stress adaptation
Title: Salt stress triggers phosphorylation of the Arabidopsis vacuolar K+ channel TPK1 by calcium-dependent protein kinases (CDPKs).

ATKCO1 can form functional potassium transport systems in E. coli
Title: Arabidopsis thaliana vacuolar TPK channels form functional K? uptake pathways in Escherichia coli.

TPK1 must assemble correctly to pass endoplasmic reticulum quality control.
Title: Assembly and sorting of the tonoplast potassium channel AtTPK1 and its turnover by internalization into the vacuole.

findings show that AtTPK1 (KCO1), interacts with 14-3-3 proteins (general regulating factors, GRFs; TPK1 seems to provide for a Ca(2+)- and 14-3-3-sensitive mechanism capable of controlling cytoplasmic potassium homeostasis in plants
Title: TPK1, a Ca(2+)-regulated Arabidopsis vacuole two-pore K(+) channel is activated by 14-3-3 proteins.

The two-pore channel TPK1 gene encodes the vacuolar K+ conductance and plays a role in K+ homeostasis.
