PYR/PYL/RCAR  receptors  to permit or enhance interaction with PP2C and thereby repress PP2C phosphatase activity. This releases SnRK2 kinases from inhibition and allow to performing various function such as;

a) phosphorylating transcription factors that bind ABA Response Elements to inhibits the ABA responsive gene expression 

b) Allow phosphorylation  ion channels for regulating  stomatal aperture 

c) phosphorylating transcription factors that bind ABA Response Elements to activates the ABA responsive gene expression
