Abscisic acid receptor complex

Abscisic acid receptor complex is a protein complex that is involved in the perception of the plant hormone abscisic acid (ABA). It is a heteromeric complex composed of three subunits: PYR/PYL/RCAR, PP2C, and SnRK2. The PYR/PYL/RCAR subunit is the ABA receptor, while the PP2C and SnRK2 subunits are negative and positive regulators of ABA signaling, respectively.
