EC Number | 2.7.11.1 |
Enzyme Function | FUNCTION: Receptor kinase involved in salt drought stress responses (PubMed:20128882). Acts as positive regulator of salt and drought tolerance (PubMed:20128882). May promote salt and drought tolerance through the induction of the activities of antioxidative enzymes, such as peroxidase, superoxide dismutase and catalase (PubMed:20128882). May be involved in the control of stomatal development in leaf epidermis (PubMed:20128882). Possesses kinase activity in vitro (PubMed:20128882). Does not seem to be involved in heat tolerance (PubMed:26280413). {ECO:0000269|PubMed:20128882, ECO:0000269|PubMed:26280413}. |
