Abstract
TANDEM ZINC-FINGER/PLUS3 (TZP) is a nuclear-localized protein with multifaceted roles in modulating plant growth and development under diverse light conditions. The unique combination of two intrinsically disordered regions (IDRs), two zinc-fingers (ZFs), and a PLUS3 domain provide a platform for interactions with the photoreceptors phytochrome A (phyA) and phyB, light signaling components, and nucleic acids. TZP controls flowering and hypocotyl elongation by regulating gene expression and protein abundance in a blue, red, or far-red light-specific context. Recently, TZP was shown to undergo liquid-liquid phase separation through its IDRs, thus promoting phyA phosphorylation. Collectively, TZP is an emerging regulator of diverse light signaling pathways; therefore, understanding its biochemical function in integrating environmental signaling networks is key for optimizing plant adaptation.
