NCBI Protein Information
phytochrome-interacting factor7
NCBI Summary
Basic helix-loop-helix (bHLH) phytochrome interacting factor. Interacts specifically with the far-red light#Aeiabsorbing 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.

UniProt Comments
Transcription 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.
