SPX3

SPX domain-containing protein 3

277 amino acids

Functional repressor of PHR2 (PubMed:24368504). Involved in maintaining cellular Pi homeostasis when plants are exposed to an external change in Pi (PubMed:24368504). Negatively regulates root-to-shoot Pi translocation redundantly with SPX3 (PubMed:24368504). Downregulates the non-coding RNA IPS1 (At3g09922) and suppresses the responses of miR399 and PHO2 to Pi-starvation (PubMed:19566645).
