GIGANTUS1 (GTS1) a member of Transducin/WD40 protein superfamily controls seed germination growth and biomass accumulation through ribosome-biogenesis protein interactions in Arabidopsis thaliana

摘要

BackgroundWD40 domains have been found in a plethora of eukaryotic proteins, acting as scaffolding molecules assisting proper activity of other proteins, and are involved in multi-cellular processes. They comprise several stretches of 44-60 amino acid residues often terminating with a WD di-peptide. They act as a site of protein-protein interactions or multi-interacting platforms, driving the assembly of protein complexes or as mediators of transient interplay among other proteins. In Arabidopsis, members of WD40 protein superfamily are known as key regulators of plant-specific events, biologically playing important roles in development and also during stress signaling.
