Mechanistic model for SA-induced changes in protein phosphorylation.
Increased protein target phosphorylation is known to occur with activation of MAP kinases as well as from MAPK phosphatases inhibition or activation of RL kinases from an unknown phosphatases inhibition. Observed decreases in protein target phosphorylation could occur by the hypothetical activation of a phosphatase or inhibition of a kinase, which resulting from interaction with the SA receptor complex NPR1/NPR3/NPR4. Both phosphatase activation and kinase inhibition also may occur indirectly. NPR: Nonexpresser of pathogenesis-related genes; MAPK: Mitogen-activated protein kinases; RL kinases: Receptor-like protein kinases.
