SPX4

SPX domain-containing protein 4

320 amino acids

Inositol polyphosphate sensor that associates with transcription factors to regulate Pi starvation responses (PubMed:27080106). The SPX domain provides a basic binding surface for inositol polyphosphate signaling molecules (PubMed:27080106). Interacts with PHR2 to inhibits its translocation to the nucleus and repress its DNA-binding activity, and then negatively regulate Pi signaling (PubMed:24692424).
