ACT — Nicotiana attenuata

Summary

A4A49_64176 (ACT) in coyote tobacco (Nicotiana attenuata) encodes an actin family protein with an actin/actin-like conserved sequence, an ATPase nucleotide-binding domain, and hydrolase activity. It is a structural constituent of the cytoskeleton and localises to the actin cytoskeleton and nucleus. The gene is associated with actin nucleation, root hair elongation, regulation of gene expression, and double fertilisation processes including pronuclear migration, karyogamy, nuclear movement, and syngamy. It is also linked to cytokinin content. Studies of related genes in other species connect the family to ATPase activity (EC 3.6.4.-).
