DESCRIPTION
Also known as PIF5_ARATH, PIF5, BHLH65, EN103, PIL6. Transcription factor acting negatively in the phytochrome B signaling pathway to promote the shade-avoidance response. Regulates PHYB abundance at the post-transcriptional level, possibly via the ubiquitin-proteasome pathway. Promotes ethylene activity in the dark. May regulate the expression of a subset of genes by binding to the G-box motif. Might be involved in the integration of light-signals to control both circadian and photomorphogenic processes. Activated by CRY1 and CRY2 in response to low blue light (LBL) by direct binding at chromatin on E-box variant 5'-CA[CT]GTG-3' to stimulate specific gene expression to adapt global physiology (e.g. hypocotyl elongation in low blue light) (PubMed:26724867). Homodimer (Probable). Interacts specifically with the Pfr form of phytochrome B and with TOC1/APRR1. May form a heterodimer with PIF3. Interacts with PHYB, CRY1 and CRY2 in the nucleus in response to low blue light (LBL) (PubMed:26724867). Interacts with TOPP4 (PubMed:26704640).
