Function
HKT22_ORYSI Seems to be involved in regulation of potassium-sodium homeostasis (PubMed:11489190, PubMed:11959905). 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 (PubMed:11489190, PubMed:11959905).[1] [2]
