G3BPs in Plant Stress

The sessile nature of plants enforces highly adaptable strategies to adapt different environmental stresses. Plants respond these stresses by a massive reprogramming mRNA metabolism. Balancing fates, including translation, sequestration, and decay is essential for not only coordinate growth development but also combat biotic abiotic RNA stress granules (SGs) processing bodies (P bodies) synchronize metabolism optimum functioning an organism. SGs are evolutionarily conserved cytoplasmic localized RNA-protein storage sites that formed in response adverse conditions, harboring mostly always translationally inactive mRNAs. disassemble release mRNAs into active form upon relief. Ras G AP SH 3 domain b inding p roteins (G3BPs or Rasputins) “scaffolds” the assembly stability SGs, which receptor mediated signal transduction with role G3BPs formation well established mammals, poorly characterized. In this review, we discuss recent findings dynamics functions plant speculate on possible mechanisms such as transcription post-translational modifications might regulate function important family proteins.
