MUF9.8 — Arabidopsis thaliana

Summary

AT5G60390 (symbol MUF9.8, also known as EF1alpha-A3) encodes a eukaryotic translation elongation factor 1 alpha (eEF1A) family protein, a GTP-binding protein with translation elongation factor activity, GTPase activity, and SUMO transferase activity. The gene is associated with numerous biological processes including nucleotide salvage, monounsaturated fatty acid anabolism, RNA folding, sterol homeostasis, plastid gene expression, sulfate assimilation, nitrate import, and cell cycle phase. It is linked to traits such as leaf necrosis, leaf curling, nitrate uptake, sugar content, photosynthetic rate, stomatal opening, abscisic acid sensitivity, flowering time, seed maturation, and root morphology. The protein localizes to multiple cellular compartments including the cytosol, chloroplast stroma, mitochondria, vacuole, nucleolus, Golgi complex, and plasmodesmata. Studies of related genes in other species connect the eEF1A family to yield, photosynthetic ability, and stress tolerance traits.
