LKS1 — Arabidopsis thaliana

Summary

AT1G30270 (LKS1, also known as CIPK23) encodes a non-specific serine/threonine protein kinase containing a NAF/FISL domain, classified as EC 2.7.11.1. In Arabidopsis, this gene is associated with potassium channel activity, nitrate transmembrane transporter activity, and protein kinase activator activity. LKS1 is linked to low potassium tolerance, potassium ion transport, ammonium ion uptake, and iron acquisition. It is associated with responses to potassium ions, nitrate transmembrane transport, magnesium ion homeostasis, and TOR signaling. The gene is associated with numerous traits including potassium concentration, nitrate content, drought sensitivity, leaf chlorophyll content, root fresh weight, root hair density and length, cadmium concentration, and water stress response. LKS1 localizes to the tonoplast, vacuole, and pollen tube, and is associated with abscisic acid-mediated signaling and responses to drought and salinity. Related genes in other species are linked to ammonium transport.
