Functional Description ? help Back to Top
Source	Description
UniProt	Transcription factor involved in phosphate starvation signaling. Binds to P1BS, an imperfect palindromic sequence 5'-GNATATNC-3', to promote the expression of inorganic phosphate (Pi) starvation-responsive genes. Functionally redundant with PHR1 and PHR3 in regulating Pi starvation response and Pi homeostasis. PHR2 binding to DNA is repressed redundantly by SPX1, SPX2 and SPX4 in a PI-dependent manner. {ECO:0000250\|UniProtKB:Q6Z156}.
UniProt	Transcription factor involved in phosphate starvation signaling (PubMed:18263782, PubMed:26082401). Binds to P1BS, an imperfect palindromic sequence 5'-GNATATNC-3', to promote the expression of inorganic phosphate (Pi) starvation-responsive genes (PubMed:25657119, PubMed:26082401). Functionally redundant with PHR1 and PHR3 in regulating Pi starvation response and Pi homeostasis (PubMed:26082401). Involved in both systematic and local Pi-signaling pathways (PubMed:19704822). Regulates several Pi transporters (PubMed:18263782). Regulates the expression of PT2 (PubMed:20149131). Directly up-regulates SPX1 and SPX2 expression, but PHR2 binding to DNA is repressed redundantly by SPX1 and SPX2 in a PI-dependent manner (PubMed:25271318). The DNA-binding activity is also repressed by SPX4 (PubMed:24692424). Involved in root growth under Pi deprivation (PubMed:18263782). {ECO:0000269\|PubMed:18263782, ECO:0000269\|PubMed:19704822, ECO:0000269\|PubMed:20149131, ECO:0000269\|PubMed:24692424, ECO:0000269\|PubMed:25271318, ECO:0000269\|PubMed:25657119, ECO:0000269\|PubMed:26082401}.
