Protein

Abscisic acid receptor PYL1

Gene

PYL1

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

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.4 Publications

Motifi112 – 1165Gate loop

Domaini

Upon interaction with ABA, the 'latch' and 'gate' loops change in conformation leading to a tight dimerization and the creation a surface that enables the receptor to dock into and inhibit the PP2C active site.
