KAT1 Antibody

1. Data show that in KAT-type K(+) channel KAT1, residue K85 within the linker forms a hydrogen bond with C211 that enables the pH activation. PMID: 26846460
2. Plant stress metabolite acrolein inhibits light-induced stomatal opening through inhibition of KAT1 potassium channels in Arabidopsis thaliana. PMID: 25144495
3. Mutations of the central Phe residue favored the closed KAT1 channel, whereas mutations affecting the countercharge centers favored the open channel PMID: 25185120
4. instead of single key amino acids, several titratable residues contribute to the pH-sensor of the plant Kin channel KAT1 PMID: 22070190
5. trafficking of KAT1 has been shown to depend on ER export signals PMID: 20712625
6. Results indicate that, in plant cells, a kinase analogous to protein kinase C might exist that may modulate KAT1 channel activity through calcium-dependent phosphorylation at some of the pinpointed residues in the cytosolic region of KAT1. PMID: 20423459
7. Phosphatidylinositol phosphates were identified as essential regulators for the voltage-dependent and -independent activation of A. thaliana potassium channels expressed in X. laevis oocytes. [KAT1] PMID: 15842627
8. KAT1 was expressed in mammalian HEK293 cells and measured with patch clamp technology in the whole cell configuration. The data show that a depletion of extracellular potassium results in a decrease in channel conductance. PMID: 16263909
9. This study demonstrated trafficking of plant plasma membrane ion channels is controlled via a conserved mechanism. PMID: 16950859
10. Structure prediction for the down state of the Kat1 voltage sensor PMID: 17187053
11. Study reports that the hormone abscisic acid, which controls ion transport and transpiration in plants under water stress, triggers the selective endocytosis of the KAT1 K+ channel protein in epidermal and guard cells. PMID: 17683934
12. The combination use of the selected detergents enabled the effective purification of functional KAT1 with affinity and gel-filtration chromatography. PMID: 18638455
