Novel protein kinases associated with calcineurin B-like calcium sensors in Arabidopsis.
The Arabidopsis SOS2 protein kinase physically interacts with and is activated by the calcium-binding protein SOS3.
-
SOS3 binds the C-terminal regulatory domain of SOS2 and activates SOS2 kinase activity in a Ca2+-dependent manner; no phosphatase partner of SOS3 was found.
"SOS3 activates SOS2 protein kinase activity in a Ca 2+ -dependent manner"
SOS3 function in plant salt tolerance requires N-myristoylation and calcium binding.
-
SOS3 binds Ca2+; the sos3-1 EF-hand deletion reduces Ca2+ binding and abolishes SOS2 interaction; myristoylation at Gly-2 is required for function in planta.
"Expression of the myristoylated but not the nonmyristoylated SOS3 complemented the salt-hypersensitive phenotype of sos3-1 plants."

Salinity-Induced Cytosolic Alkaline Shifts in Arabidopsis Roots Require the SOS Pathway.
An Arabidopsis mutant that requires increased calcium for potassium nutrition and salt tolerance.
-
sos3 is hypersensitive to Na+ and Li+, cannot grow on low K+, accumulates more Na+ and less K+ under NaCl, and is rescued by high external Ca2+.

Calcium-dependent modulation and plasma membrane targeting of the AKT2 potassium channel by the CBL4/CIPK6 calcium sensor/protein kinase complex.
Phosphorylation of calcineurin B-like (CBL) calcium sensor proteins by their CBL-interacting protein kinases (CIPKs) is required for full activity of CBL-CIPK complexes toward their target proteins.
Arabidopsis SOS3 plays an important role in salt tolerance by mediating calcium-dependent microfilament reorganization.
