Gene
PYL4
Protein
Abscisic acid receptor PYL4
Organism
Arabidopsis thaliana
Length
207 amino acids
Function
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:19624469, PubMed:23844015, PubMed:21658606). Can be activated by both (-)-ABA and (+)-ABA (PubMed:23844015).
Similarity
Belongs to the PYR/PYL/RCAR abscisic acid intracellular receptor family.
