STRINGSTRING
KAB1 protein (Arabidopsis thaliana) - STRING interaction network
"KAB1" - Potassium channel beta subunit 1 in Arabidopsis thaliana
Nodes:
Network nodes represent proteins
splice isoforms or post-translational modifications are collapsed, i.e. each node represents all the proteins produced by a single, protein-coding gene locus.
Node Color
colored nodes:
query proteins and first shell of interactors
white nodes:
second shell of interactors
Node Content
empty nodes:
proteins of unknown 3D structure
filled nodes:
some 3D structure is known or predicted
Edges:
Edges represent protein-protein associations
associations are meant to be specific and meaningful, i.e. proteins jointly contribute to a shared function; this does not necessarily mean they are physically binding each other.
Known Interactions
from curated databases
experimentally determined
Predicted Interactions
gene neighborhood
gene fusions
gene co-occurrence
Others
textmining
co-expression
protein homology

KAB1Potassium channel beta subunit 1; Probable accessory potassium channel protein which modulates the activity of the pore-forming alpha subunit (328 aa)    
Predicted Functional Partners:
KAT1
Potassium channel KAT1; Highly selective inward-rectifying potassium channel. This voltage-gated channel could mediate long-term potassium influx into guard cells leading to stomatal opening. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by hyperpolarization. The channel activity is enhanced upon external acidification. Also permeable to ammonium ions. Blocked by tetraethylammonium and barium ions (677 aa)
       
  0.983
KT5
K+ transporter 5; Probable potassium channel. May interact with the cytoskeleton or with regulatory proteins (By similarity) (880 aa)
       
  0.968
AKT1
K+ transporter 1; Highly selective inward-rectifying potassium channel that mediate potassium uptake by plant roots in response to low K(+) conditions, by a calcium-, CBL-, and CIPK-dependent pathway. Positively regulated by phosphorylation by CIPK23. Negatively regulated by a kinase-independent regulatory mechanism involving a competing direct binding of CBL10. Involved in the stomatal regulation by monitoring the turgor pressure in guard cells. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by hyperpolarizat [...] (857 aa)
       
  0.964
SPIK
Shaker pollen inward K+ channel; Highly selective inward-rectifying potassium channel that could mediate potassium uptake in the pollen membrane. Plays an important role in pollen tube development. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by hyperpolarization. May interact with the cytoskeleton or with regulatory proteins (888 aa)
       
  0.962
KT2/3
Potassium transport 2/3; Highly selective and weak inward-rectifying potassium channel. Plays a role in both loading and unloading potassium into/from the phloem sap. Seems to control sugar loading into phloem via a voltage-dependent process. Blocked by physiological concentrations of external calcium and by external acidification. May interact with the cytoskeleton or with regulatory proteins. Dephosphorylation by PP2CA not only leads to the inhibition of potassium currents but also to an increase of the voltage- dependence of the channel. Regulated by the CBL4/CIPK6 calcium sensor/pr [...] (802 aa)
       
  0.952
KAT3
Potassium channel KAT3; Probable modulatory (alpha) subunit of inward-rectifying potassium channels. Could mediate potassium uptake from the soil solution by plant roots in association with AKT1 (662 aa)
       
  0.950
SKOR
Potassium channel SKOR; Highly selective outward-rectifying potassium channel. Involved in potassium release into the xylem sap toward the shoots. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by depolarization. The voltage-dependence of the channel is abolished by internal or external acidification. May interact with the cytoskeleton or with regulatory proteins (828 aa)
       
  0.946
GORK
Potassium channel GORK; Major selective outward-rectifying potassium channel of the guard cell membrane. Involved in regulation of stomatal movements according to the water status. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by depolarization. Conductance of the channel is modulated in a potassium-dependent fashion. May interact with the cytoskeleton or with regulatory proteins (820 aa)
       
  0.946
KAT2
Potassium channel KAT2; Highly selective inward-rectifying potassium channel. This voltage-dependent channel could mediate long-term potassium influx into guard cells leading to stomatal opening. Assuming opened or closed conformations in response to the voltage difference across the membrane, the channel is activated by hyperpolarization. The channel activity is enhanced upon external acidification (697 aa)
