Gene Symbol
- Os02g0202200 <=> SPX2,OsSPX2
Function
- SPX2 is Pi-dependent inhibitors of the activity of OsPHR2 in rice.
- SPX1 and SPX2 proteins interact with PHR2 through their SPX domain, inhibiting its binding to P1BS (the PHR1-binding sequence: GNATATNC)
- SPX2 is critical for repressing PHR2 binding to cis ele-ments by protein interaction
Subcellular localization
- Subcellular localization analysis demonstrated that SPX2 was mainly localized in the nucleus.
