AKT1 — Beta vulgaris subsp. vulgaris

Summary

BvAKT6 (gene BVRB_7G179310, symbol AKT1) on sugar beet chromosome Bvchr7_un.sca007 encodes an uncharacterized protein with an ankyrin-SOCS box domain and ankyrin repeats, associated with voltage-sensitive potassium channel and ubiquitin ligase activities, as well as zinc binding. The gene is associated with protein ubiquitination, including K6-linked ubiquitination and autoubiquitination, and with processes such as phosphate ion detection, response to oxidative stress, and defence responses to bacteria. It is also associated with nodulation, arbuscular mycorrhizae formation, and responses to symbiotic bacteria and fungi, with localisation at the plasmalemma, periarbuscular membrane, cytosol, and nucleus. Related genes in other species link the family to similar ubiquitination and stress-related functions.
