ACT — Nicotiana attenuata

Summary

A4A49_65510 (ACT, AC71) in coyote tobacco (Nicotiana attenuata) encodes an actin protein, a structural constituent of the cytoskeleton with ATP binding and hydrolase activity. It is associated with the actin cytoskeleton and cytosol, and is linked to processes including actin nucleation, cell division, root hair elongation, pronuclear migration, karyogamy, nuclear movement, double fertilization, syngamy, and regulation of gene expression. The gene is also associated with cytokinin content. Studies of related genes in other species link the family to ATPase activity (EC 3.6.4.-).
