Crystal structure of native abscisic acid receptor PYL5 at 2.65 Angstrom

Template:ABSTRACT PUBMED 23844015

Function

[PYL5_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. Confers enhanced sensitivity to ABA.^{[1] [2]}

About this Structure
