Protein PHOSPHATE STARVATION RESPONSE 2 antibody; OsPHR2 antibody ; PHR2 antibody
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 . Involved in both systematic and local Pi-signaling pathways. Regulates several Pi transporters . Regulates the expression of PT2 . Directly up-regulates SPX1 and SPX2 expression, but PHR2 binding to DNA is repressed redundantly by SPX1 and SPX2 in a PI-dependent manner . The DNA-binding activity is also repressed by SPX4. Involved in root growth under Pi deprivation.
