ACT — Nicotiana attenuata

Summary

A4A49_55731 (ACT) 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 linked to processes including actin nucleation, root hair elongation, pronuclear migration, karyogamy, nuclear movement, double fertilization, syngamy, and regulation of gene expression. The gene has also been connected to cytokinin content. Studies of related genes in other species place this family within the ATPase superfamily (EC 3.6.4.-), though such functional assignments are not directly established for this gene.
