STRINGSTRING
STO protein (Arabidopsis thaliana) - STRING interaction network
"STO" - B-box zinc finger family protein 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

STOB-box zinc finger family protein; Acts as negative regulator of seedling photomorphogenesis and light-regulated inhibition of hypocotyl elongation. 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. Functions as negative regulator of photomorphogenic UV-B responses by interacting with both COP1 and HY5. May act as a transcription factor in the salt-stress response (248 aa)    
Predicted Functional Partners:
COP1
Transducin/WD40 repeat-like superfamily protein; E3 ubiquitin-protein ligase that acts as a repressor of photomorphogenesis and as an activator of etiolation in darkness. E3 ubiquitin ligases accept ubiquitin from an E2 ubiquitin- conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Represses photomorphogenesis in darkness by mediating ubiquitination and subsequent proteasomal degradation of light-induced transcription factors such as HY5, HYH and LAF1. Down-regulates MYB21, probably via ubiquitination process. Light stimuli ab [...] (675 aa)

AT5G64170
Dentin sialophosphoprotein-related; Transcriptional coactivator necessary for expression of the clock genes PRR5 and TOC1. Antagonizes REV8 function in the regulation of anthocyanin accumulation. Involved in red light input to the clock. Activates clock-controlled genes with afternoon peak. Mediates light inhibition of hypocotyl elongation (616 aa)
     
        0.850
CDF3
Cycling DOF factor 3; Dof-type zinc finger domain-containing protein, identical to H-protein promoter binding factor-2a GI-3386546 from (Arabidopsis thaliana). Interacts with LKP2 and FKF1, but its overexpression does not change flowering time under short or long day conditions (448 aa)
     
   
  0.835
HY5
Basic leucine zipper (bZIP) transcription factor. Nuclear localization. Involved in light-regulated transcriptional activation of G-box-containing promoters. Negatively regulated by Cop1. Although cytokinins do not appear to affect the gene’s promoter activity, they appear to stabilize the protein. HY5 plays a role in anthocyanin accumulation in far-red light and blue light, but not in red light or in the dark. Mutant studies showed that the gene product is involved in the positive regulation of the PHYA-mediated inhibition of hypocotyl elongation. Binds to G- and Z-boxes, and other AC [...] (168 aa)

AT5G06980
Protein LNK4; Probable transcriptional coactivator (279 aa)
     
        0.811
PHT4;1
Sodium-dependent phosphate transport protein 1, chloroplastic; Specific for inorganic phosphate transport across the thylakoid membrane in a sodium dependent manner. Binds glutamate but cannot transport it. May act as an ascorbate transporter at the thylakoid membrane (Probable); Belongs to the major facilitator superfamily. Sodium/anion cotransporter (TC 2.A.1.14) family (512 aa)
     
        0.799
BBX32
B-box zinc finger protein 32; Repressor of light-mediated regulation of seedling development. Functions by suppressing the activities of positive cofactors like BBX21 and HY5 involved in modulating light- regulated gene expression and growth (225 aa)
       
 
  0.746
AT3G12320
Protein LNK3; Probable transcriptional coactivator (269 aa)
     
        0.739
AT3G54500
Protein LNK2; Transcriptional coactivator necessary for expression of the clock genes PRR5 and TOC1. Antagonizes REV8 function in the regulation of anthocyanin accumulation. Involved in red light input to the clock. Activates clock-controlled genes with afternoon peak. Mediates light inhibition of hypocotyl elongation. Unable to bind to DNA, but recruited to the evening element (EE)-containing region of the PRR5 and TOC1 promoters through its interaction with the DNA binding proteins REV8 and REV4 (669 aa)
     
        0.738
ABA1
Zeaxanthin epoxidase, chloroplastic; 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 norma [...] (667 aa)
