SPX domain gene 4 | Brief Description | SPX domain-containing protein 4 |
| TAIR Computational Description | SPX domain-containing protein 4;(source:Araport11) |
| TAIR Curator Summary | Encodes a protein with a single SYG1/Pho81/XPR1 (SPX) domain that localizes to both the cytosol and nucleus, acting as a dose-dependent modulator of PHR1-dependent and PHR1-independent phosphate-starvation responses in shoots. SPX4 prevents translocation of PHR1 (AT4G28610) to the nucleus in a dose- and Pi-dependent manner. In contrast to SPX1, SPX4 modulates rather than suppresses phosphate-starvation response (PSR) gene expression. |
