ARABIDOPSIS NA+/H+ ANTIPORTER 7, ARABIDOPSIS SALT OVERLY SENSITIVE 1, ATNHX7, ATSOS1, F14H20.5, F14H20_5, SALT OVERLY SENSITIVE 1, SOS1 |
| Description: |
|
Encodes a plasma membrane-localized Na+/H+ antiporter SOS1. Functions in the extrusion of toxic Na+ from cells and is essential for plant salt tolerance. Has 12 predicted transmembrane domains in the N-terminal region and a long cytoplasmic tail of approx. 700 aa at the C-terminal side. SOS1 interacts through its predicted cytoplasmic tail with RCD1, a regulator of oxidative-stress responses, suggesting that SOS1 might function in oxidative-stress tolerance. |
