STRINGSTRING
STO protein (Arabidopsis thaliana) - STRING interaction network
"STO" - SALT TOLERANCE 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

STOSALT TOLERANCE; Acts as negative regulator of seedling photomorphogenesis and light-regulated inhibition of hypocotyl elongation (PubMed-17605755, PubMed-18540109, PubMed-21685177). BBX24/STO and BBX25/STH function as transcriptional corepressors of HY5 activity, leading to the down-regulation of BBX22 expression. BBX24/STO acts additively with BBX25/STH during de- etiolation and the hypocotyl shade avoidance response (PubMed-23624715). Functions as negative regulator of photomorphogenic UV-B responses by interacting with both COP1 and HY5 (PubMed-22410790). May act as a transcription [...] (248 aa)    
Predicted Functional Partners:
NHX1
Na+/H+ exchanger 1; Acts in low affinity electroneutral exchange of protons for cations such as Na(+) or K(+) across membranes. Can also exchange Li(+) and Cs(+) with a lower affinity. Involved in vacuolar ion compartmentalization necessary for cell volume regulation and cytoplasmic Na(+) detoxification. Required during leaves expansion, probably to stimulate epidermal cell expansion. Confers competence to grow in high salinity conditions (538 aa)
           
  0.981
SOS1
SALT OVERLY SENSITIVE 1; Acts in electroneutral exchange of protons for cations such as Na(+) or Li(+) across plasma membrane. Involved in Na(+) and K(+) homeostasis. Required for cytoplasmic Na(+) and Li(+) detoxification by secreting them from the cytoplasm to the extracellular space. Regulates Na(+) content of the xylem sap (1146 aa)
           
  0.961
SOS3
SALT OVERLY SENSITIVE 3; Acts as a calcium sensor involved in the regulatory pathway for the control of intracellular Na(+) and K(+) homeostasis and salt tolerance. Binding of a CBL protein to the regulatory NAF domain of a CIPK serine-threonine protein kinase lead to the activation of the kinase in a calcium-dependent manner. Operates in synergy with CIPK24/SOS2 to activate the plasma membrane Na(+)/H(+) antiporter SOS1. Involved in salt stress responses by mediating calcium-dependent microfilament reorganization. The CBL4/CIPK6 complex mediates translocation of AKT2 from the endoplas [...] (222 aa)
           
  0.960
HKT1
Sodium transporter HKT1; Sodium transporter protein, which plays a central role in plant tolerance to salt. Upon prolongated exposure to high concentrations, Na(+) translocates from the roots to the transpiring leaves where it can increase to toxic level. Involved in Na(+) recirculation from shoots to roots, probably by mediating Na(+) loading into the phloem sap in shoots and unloading in roots, thereby removing large amounts of Na(+) from the shoot. Does not transport K(+) but regulates K(+) nutrient status via its ability to facilitate Na(+) homeostasis. Probably not involved in roo [...] (506 aa)
           
  0.960
SOS2
SALT OVERLY SENSITIVE 2; Involved in the regulatory pathway for the control of intracellular Na(+) and K(+) homeostasis and salt tolerance. Activates the vacuolar H(+)/Ca(2+) antiporter CAX1 and operates in synergy with CBL4/SOS3 to activate the plasma membrane Na(+)/H(+) antiporter SOS1. CIPK serine-threonine protein kinases interact with CBL proteins. Binding of a CBL protein to the regulatory NAF domain of CIPK protein lead to the activation of the kinase in a calcium-dependent manner. Phosphorylates CBL1, CBL4 and CBL10 (446 aa)
           
  0.958
ABA1
ABA DEFICIENT 1; Zeaxanthin epoxidase that plays an important role in the xanthophyll cycle and abscisic acid (ABA) biosynthesis. Converts zeaxanthin into antheraxanthin and subsequently violaxanthin. Required for resistance to osmotic and drought stresses, ABA- dependent stomatal closure, seed development and dormancy, modulation of defense gene expression and disease resistance and non-photochemical quencing (NPQ). Through its role in ABA biosynthesis, regulates the expression of stress-responsive genes such as RD29A during osmotic stress and is required for normal plant growth durin [...] (667 aa)
     
   
  0.905
LTI78
LOW-TEMPERATURE-INDUCED 78 (710 aa)
           
  0.872
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)
           
  0.862
bZIP
Basic leucine-zipper 8 (138 aa)
           
  0.861
AVP1
Pyrophosphate-energized vacuolar membrane proton pump 1; Contributes to the transtonoplast (from cytosol to vacuole lumen) H(+)-electrochemical potential difference. It establishes a proton gradient of similar and often greater magnitude than the H(+)-ATPase on the same membrane. In addition, facilitates auxin transport by modulating apoplastic pH and regulates auxin-mediated developmental processes. Confers tolerance to NaCl and to drought by increasing ion retention (770 aa)
