Web18 May 2024 · The in vivo interaction of PHR1 and SPX1 is influenced by P i 3, 4, 5, suggesting that this mechanism could represent a direct link between P iperception and downstream signaling events. However, the dissociation constants for P iitself in a SPX-PHR complex ranged from 10 mM to 20 mM3, 4, 5, while P Web14 Oct 2014 · Here, we show that the nuclear localized SPX proteins SPX1 and SPX2 are Pi-dependent inhibitors of the activity of OsPHR2 in rice. Indeed, SPX1 and SPX2 proteins interact with PHR2 through their SPX domain, inhibiting its binding to P1BS (the PHR1-binding sequence: GNATATNC). In vivo data, as well as results from in vitro experiments …
