ACT — Nicotiana attenuata

Summary

A4A49_26171 (ACT) in coyote tobacco (Nicotiana attenuata) encodes an actin family protein, specifically AC101, which is a structural constituent of the cytoskeleton with ATP binding and hydrolase activity. It localizes to the actin cytoskeleton and nucleus. The gene is associated with pronuclear migration, karyogamy, nuclear movement, actin nucleation, double fertilization, syngamy, root hair elongation, and regulation of gene expression. It has also been linked to cytokinin content. Studies of related genes in other species connect the family to broader cytoskeletal functions, including ATPase activity (EC 3.6.4.-).
