ABA-mimicking ligand QUINABACTIN in complex with ABA receptor PYL2 and PP2C HAB1ABA-mimicking ligand QUINABACTIN in complex with ABA receptor PYL2 and PP2C HAB1
Template:ABSTRACT PUBMED 23835477
FunctionFunction
[PYL2_ARATH] 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.[1] [2] [P2C16_ARATH] Key component and repressor of the abscisic acid (ABA) signaling pathway that regulates numerous ABA responses, such as stomatal closure, seed germination and inhibition of vegetative growth. Confers enhanced sensitivity to drought.[3] [4] [5] [6]
