"PIF3" - Transcription factor PIF3 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

PIF3Transcription factor PIF3; Transcription factor acting positively in the phytochrome signaling pathway. Activates transcription by binding to the G box (5’-CACGTG-3’) (524 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)

RGA1
DELLA protein RGA; Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. Probably acts by participating in large multiprotein complexes that repress transcription of GA-inducible genes. Positively regulates XERICO expression in seeds. Upon GA application, it is degraded by the proteasome, allowing the GA signaling pathway. Compared to other DELLA proteins, it is the most sensitive to GA application. No effect of the BOI proteins on its stability. Its activity is probably regulated by other phytohormones such as auxin and ethylene, attenu [...] (587 aa)

GAI
DELLA protein GAI; Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. No effect of the BOI proteins on its stability. Probably acts by participating in large multiprotein complexes that repress transcription of GA- inducible genes. Positively regulates XERICO expression. In contrast to RGA, it is less sensitive to GA. Its activity is probably regulated by other phytohormones such as auxin and ethylene (533 aa)

RGL1
RGA-like 1; Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. No effect of the BOI proteins on its stability. Probably acts by participating in large multiprotein complexes that repress transcription of GA- inducible genes. Has overlapping but distinct roles in GA signaling compared to RGA and GAI. Regulates the floral development. May also participate in seed germination and in ovule and anther development. Its activity is probably regulated by other phytohormones such as auxin and ethylene (511 aa)

RGL3
DELLA protein RGL3; Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. No effect of the BOI proteins on its stability. Probably acts by participating in large multiprotein complexes that repress transcription of GA- inducible genes. Its activity may be regulated by phytohormones such as auxin and ethylene (By similarity) (523 aa)

RGL2
RGA-like 2; Probable transcriptional regulator that acts as a repressor of the gibberellin (GA) signaling pathway. No effect of the BOI proteins on its stability. Probably acts by participating in large multiprotein complexes that repress transcription of GA- inducible genes. Upon GA application, it is degraded by the proteasome, allowing the GA signaling pathway. Acts as a major GA- response repressor of seed germination, including seed thermoinhibition. Promotes the biosynthesis of abscisic acid (ABA), especially in seed coats to maintain seed dormancy. Delays flowering and adult lea [...] (547 aa)

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)
