ACT — Nicotiana attenuata

Summary

A4A49_33830 (ACT) in coyote tobacco (Nicotiana attenuata) encodes an actin protein, a structural constituent of the cytoskeleton with ATP-binding and hydrolase activity. It belongs to the actin/actin-like and ATPase NBD families. This gene is associated with actin nucleation, root hair elongation, regulation of gene expression, and double fertilization processes including pronuclear migration, karyogamy, nuclear movement, and syngamy. It localizes to the actin cytoskeleton. The gene has also been connected to cytokinin content. Related genes in other species link the family to ATPase activity (EC 3.6.4.-).
