ACT — Nicotiana attenuata

Summary

A4A49_40222 (ACT7) in coyote tobacco (Nicotiana attenuata) encodes a protein with an ATPase_NBD domain and multiple molecular functions including actin, phospholipid, profilin, and F-actin binding, as well as protein serine/threonine phosphatase activity. It is a structural constituent of the cytoskeleton. The gene is associated with actin filament-based processes including nucleation, stabilization, depolymerization, and capping, as well as cytoskeleton organization, cell tip growth, nuclear movement, and Golgi-to-plasma membrane transport. It localizes to the actin cytoskeleton, Golgi membrane, endosome, and chloroplast envelope. ACT7 is associated with seed morphology and yield, leaf area, vegetative vigor, root hair length, shoot branching, water stress response, nitrogen and potassium sensitivity, aphid response, and powdery mildew disease response. Related genes in other species are linked to drought resistance, osmotic stress tolerance, hypersensitive response, and leaf senescence.
