Gene
NHX7
Protein
Sodium/hydrogen exchanger 7
Organism
Arabidopsis thaliana
Length
1146 amino acids
Function
Acts in electroneutral exchange of protons for cations such as Na(+) or Li(+) across plasma membrane. Involved in Na(+) and K(+) homeostasis. Required for cytoplasmic Na(+) and Li(+) detoxification by secreting them from the cytoplasm to the extracellular space. Regulates Na(+) content of the xylem sap.
Similarity
Belongs to the monovalent cation:proton antiporter 1 (CPA1) transporter (TC 2.A.36) family.
