STRINGSTRING
HFR1 protein (Arabidopsis thaliana) - STRING interaction network
"HFR1" - LONG HYPOCOTYL IN FAR-RED 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

HFR1LONG HYPOCOTYL IN FAR-RED; Atypical bHLH transcription factor that regulates photomorphogenesis through modulation of phytochrome and cryptochrome signalings. Suppresses the transcriptional regulation activity of PIF4 by forming non-DNA-binding heterodimer (292 aa)    
Predicted Functional Partners:
PHYA
Phytochrome A; Regulatory photoreceptor which exists in two forms that are reversibly interconvertible by light- the Pr form that absorbs maximally in the red region of the spectrum and the Pfr form that absorbs maximally in the far-red region. Photoconversion of Pr to Pfr induces an array of morphogenetic responses, whereas reconversion of Pfr to Pr cancels the induction of those responses. Pfr controls the expression of a number of nuclear genes including those encoding the small subunit of ribulose- bisphosphate carboxylase, chlorophyll A/B binding protein, protochlorophyllide reduc [...] (1122 aa)

PHYB
Phytochrome B; Regulatory photoreceptor which exists in two forms that are reversibly interconvertible by light- the Pr form that absorbs maximally in the red region of the spectrum and the Pfr form that absorbs maximally in the far-red region. Photoconversion of Pr to Pfr induces an array of morphogenetic responses, whereas reconversion of Pfr to Pr cancels the induction of those responses. Pfr controls the expression of a number of nuclear genes including those encoding the small subunit of ribulose- bisphosphate carboxylase, chlorophyll A/B binding protein, protochlorophyllide reduc [...] (1172 aa)

COP1
CONSTITUTIVE PHOTOMORPHOGENIC 1; 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 abrogate the repre [...] (675 aa)
       
 
  0.965
LAF1
Transcription factor LAF1; Transcription factor that promotes photomorphogenesis in the light by participating in the transmission of phytochrome A (phyA) signals to downstream responses. Probably acts by activating expression of light-induced genes. In darkness, its degradation prevents the activation of light-induced genes (283 aa)
       
 
  0.964
SPA1
SUPPRESSOR OF PHYA-105 1; Controls normal photoperiodic flowering and regulates circadian rhythms. Required for suppression of photomorphogenesis in dark-grown seedlings and for normal elongation growth of adult plants. Integral component of the COP1/SPA E3 ubiquitin-protein ligase complex. Involved in HY5, HFR1, LAF1 and CO degradation (1029 aa)
       
 
  0.963
HY5
ELONGATED HYPOCOTYL 5; Transcription factor that promotes photomorphogenesis in light. Acts downstream of the light receptor network and directly affects transcription of light-induced genes. Specifically involved in the blue light specific pathway, suggesting that it participates in transmission of cryptochromes (CRY1 and CRY2) signals to downstream responses. In darkness, its degradation prevents the activation of light-induced genes (168 aa)
       
 
  0.949
KDR
KIDARI; Atypical and probable non DNA-binding bHLH transcription factor that regulates light-mediated responses in day light conditions by binding and inhibiting the activity of the bHLH transcription factor HFR1, a critical regulator of light signaling and shade avoidance. Forms non-functional heterodimers with HFR1, causing liberation and activation of PIF4 from the transcriptionally inactive HFR1-PIF4 complex (94 aa)

Phytochrome E; Regulatory photoreceptor which exists in two forms that are reversibly interconvertible by light- the Pr form that absorbs maximally in the red region of the spectrum and the Pfr form that absorbs maximally in the far-red region. Photoconversion of Pr to Pfr induces an array of morphogenic responses, whereas reconversion of Pfr to Pr cancels the induction of those responses. Pfr controls the expression of a number of nuclear genes including those encoding the small subunit of ribulose- bisphosphate carboxylase, chlorophyll A/B binding protein, protochlorophyllide reducta [...] (1112 aa)
