UniProtKB description: Regulates chlorophyll synthesis and plastid-to-nucleus signal transduction by binding both the product and the substrate of Mg-chelatase, an enzyme that produces magnesium-protoporphyrin IX (Mg-Proto). Activates also Mg-chelatase. Neither binds abscisic acid (ABA) nor is involved in ABA signaling.
