- FUNCTION: Seems to be involved in regulation of K(+)/Na(+) homeostasis. Seems to act as a potassium-sodium cotransporter, which mediates increased potassium uptake under external sodium accumulation and contributes to salt-tolerance in cultivar indica Pokkali.
- SUBCELLULAR LOCATION: Membrane; Multi-pass membrane protein (Probable).
- INDUCTION: By potassium starvation in roots. Down-regulated by sodium.
- DOMAIN: HKT transporters are proposed to contain 4 pore-forming regions enclosed by transmembrane segments with each containing a potassium channel-like selectivity filter motif.
- SIMILARITY: Belongs to the trkH potassium transport family. HKT subfamily.
- CAUTION: HKT2 is found in salt-tolerant cultivar indica Pokkali. It does not exist in cultivar indica 93-11 or japonica Nipponbare.
