Functional Description ? help Back to Top
Source Description
TAIRBasic helix-loop-helix (bHLH) phytochrome interacting factor. Interacts specifically with the far-red lightabsorbing Pfr form of phyB through a conserved domain called the active phyB binding motif. Upon light exposure, PIF7 rapidly migrates to intranuclear speckles, where it colocalizes with phyB. Role as negative regulator of phyB-mediated seedling deetiolation.
UniProtTranscription factor acting negatively in the phytochrome B signaling pathway under prolonged red light. Regulates PHYB abundance at the post-transcriptional level, possibly via the ubiquitin-proteasome pathway. May regulate the expression of a subset of genes by binding to the G-box motif. {ECO:0000269|PubMed:15486100, ECO:0000269|PubMed:18252845}.
Function -- GeneRIF ? help Back to Top
  1. Data provide evidence that the mechanism by which PIF7 operate on the phyB signaling pathway under prolonged red light is through maintaining low phyB protein levels, in an additive or synergistic manner.
    [PMID: 18252845]
  2. PIF7 functions as a transcriptional repressor for DREB1C expression and its activity is regulated by PIF7-interacting factors TIMING OF CAB EXPRESSION1 and Phytochrome B.
    [PMID: 19837816]
  3. New auxin synthesized through a PIF7-regulated pathway is required for shade-induced growth, linking directly the perception of a light quality signal to a rapid growth response.
