NUT — Nicotiana attenuata

Summary

A4A49_07281 (NUT) in coyote tobacco (Nicotiana attenuata) encodes a G-type lectin S-receptor-like serine/threonine-protein kinase, possessing protein serine/threonine kinase activity, ATP binding, sugar binding, and identical protein binding. It is localized to the membrane. This gene is associated with pollen recognition and rejection of self pollen, linking it to self-incompatibility. It is also associated with defense response, response to other organisms, autophagy, lignin anabolism, secretion, lateral root and root development, cell growth, virus-induced PTGS, and homeostasis. Related genes in other species, such as SRK and LECRK, link the family to similar signaling roles, including the non-specific serine/threonine protein kinase activity (EC 2.7.11.1).
