Crystal structure of pyrabactin bound abscisic acid receptor PYL2 mutant A93F in complex with type 2C protein phosphatase HAB1
Template:ABSTRACT PUBMED 20729862
Function
[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]
