STRINGSTRING
OZS1 protein (Arabidopsis thaliana) - STRING interaction network
"OZS1" - OZONE-SENSITIVE 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

OZS1OZONE-SENSITIVE 1; Slow, weak voltage-dependent S-type anion efflux channel involved in maintenance of anion homeostasis. Cl(-) efflux through SLAC1 causes membrane depolarization, which activates outward- rectifying K1 channels, leading to KCl and water efflux to reduce turgor further and cause stomatal closure, that reduces water loss and promotes leaf turgor. Essential for stomatal closure in response to CO(2), abscisic acid (ABA), ozone O(3), light/dark transitions, humidity change, calcium ions, hydrogen peroxide H(2)O(2), reactive oxygen species (ROS), and nitric oxide (556 aa)    
Predicted Functional Partners:
OST1
OPEN STOMATA 1; Activator of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as stomata closure in response to drought, plant pathogens, or decreases in atmospheric relative humidity (RH). Involved in the resistance to drought by avoiding water loss. Required for the stomata closure mediated by pathogen-associated molecular pattern (PAMPs) (e.g. flg22 and LPS) of pathogenic bacteria such as P.syringae pv. tomato (Pst) and E.coli O157-H7. As a plant defense process, stomata are closed transiently in order to limit invaders, but actively reopened by [...] (362 aa)

CPK23
Calcium-dependent protein kinase 23; May play a role in signal transduction pathways that involve calcium as a second messenger. Could act as a calcium sensor involved in drought- and salt stress-induced calcium signaling cascades. Mediates the phosphorylation and activation of the S-type anion efflux channel SLAC1 (533 aa)
       
 
  0.970
PP2CA
Protein phosphatase 2CA; Major negative regulator of abscisic acid (ABA) responses during seed germination and cold acclimation. Confers insensitivity to ABA. Modulates negatively the AKT2/3 activity, which mediates K(+) transport and membrane polarization during stress situations, probably by dephosphorylation. Prevent stomata closure by inactivating the S-type anion efflux channel SLAC1 and its activator SRK2E (399 aa)
       
 
  0.961
CPK6
Calcium dependent protein kinase 6; May play a role in signal transduction pathways that involve calcium as a second messenger. Functions in abscisic acid (ABA) regulation of guard cell S-type anion-and Ca(2+)-permeable channels and stomatal closure (544 aa)
       
 
  0.951
CPK21
Calcium-dependent protein kinase 21; May play a role in signal transduction pathways that involve calcium as a second messenger. Mediates the phosphorylation and activation of the S-type anion efflux channel SLAC1 (531 aa)
       
 
  0.950
CDPK6
Calcium-dependent protein kinase 6; May play a role in signal transduction pathways that involve calcium as a second messenger. Functions in abscisic acid (ABA) regulation of guard cell S-type anion-and Ca(2+)-permeable channels and stomatal closure (529 aa)
       
 
  0.946
SNRK2.2
SNF1-related protein kinase 2.2; Together with SRK2I, key component and activator of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as seed germination, Pro accumulation, root growth inhibition, dormancy and seedling growth, and, to a lesser extent, stomatal closure (369 aa)
       
 
  0.891
SNRK2.3
Serine/threonine-protein kinase SRK2I; Together with SRK2D, key component and activator of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as seed germination, Pro accumulation, root growth inhibition, dormancy and seedling growth, and, to a lesser extent, stomatal closure (361 aa)
       
 
  0.865
ABI1
ABA INSENSITIVE 1; Key component and repressor of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as stomatal closure, osmotic water permeability of the plasma membrane (Pos), drought-induced resistance and rhizogenesis, response to glucose, high light stress, seed germination and inhibition of vegetative growth. During the stomatal closure regulation, modulates the inward calcium-channel permeability as well as the actin reorganization in guard cells in response to ABA. Involved in the resistance to the bacterial pathogen Pseudomonas syringae pv. [...] (434 aa)
           
  0.863
ALMT12
Aluminum-activated, malate transporter 12; Malate-sensitive anion transporter permeable to chloride, nitrate, sulfate and malate. Involved in dark-, CO(2)-, abscisic acid- and water-deficient-induced stomatal closure. Belongs to the R-type anion channels (560 aa)
