NUT — Nicotiana attenuata

Summary

A4A49_07134 (NUT) in coyote tobacco (Nicotiana attenuata) encodes a non-specific serine/threonine protein kinase belonging to the plant LRR-RLK family. It is associated with transmembrane receptor protein kinase activity, steroid and SNARE binding, and signaling receptor activity. The gene is linked to diverse biological processes including autophagy, defense response upregulation, lignin anabolism, microtubule bundling, megasporogenesis, anther wall tapetum development, skotomorphogenesis, secretion, microsporogenesis, lateral root development, virus-induced PTGS, brassinosteroid stimulus detection, hormone-mediated signaling, cell growth, response to other organisms, and heat acclimation. It localizes to the perinuclear ER membrane, cortical ER, endosome, ER membrane, plasmalemma, nucleus, and extracellular space. The gene is also associated with self-incompatibility. Studies of related genes in other species link the family to immune and developmental signaling.
