ACT — Nicotiana attenuata

Summary

A4A49_09715 (ACT, AC101) in coyote tobacco (Nicotiana attenuata) encodes an actin family protein with a structural constituent of the cytoskeleton role, also annotated for hydrolase activity and ATP binding. It is associated with the actin cytoskeleton and nucleus, and has been linked to processes including actin nucleation, 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 hydrolase activity (EC 3.6.4.-).
