FAMILY

PYR/PYL/RCAR abscisic acid intracellular receptor family

DESCRIPTION

Also known as PYL2_ARATH, PYL2, RCAR14. Receptor for abscisic acid (ABA) required for ABA-mediated responses such as stomatal closure and germination inhibition. Inhibits the activity of group-A protein phosphatases type 2C (PP2Cs) when activated by ABA (PubMed:19893533, PubMed:19898420, PubMed:23844015, PubMed:21658606). Can be activated by both (-)-ABA and (+)-ABA (PubMed:23844015). Homodimer (PubMed:19898420, PubMed:21658606). Binds ABA on one subunit only. Interacts with HAB1, ABI1 and ABI2, and possibly with other PP2Cs (PubMed:19407142, PubMed:19893533, PubMed:19898420). Binds to CARs protein in an ABA-independent manner, both at the plasma membrane and in the nucleus (By similarity).
