General annotation (Comments)

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 By similarity.

Subunit structure

Homodimer. Binds ABA on one subunit only By similarity. Interacts with ABI1, and possibly with other PP2Cs. Ref.5

Subcellular location

Cytoplasm By similarity. Nucleus By similarity.

Domain

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 By similarity.

Sequence similarities

Belongs to the PYR/PYL/RCAR abscisic acid intracellular receptor family.

Sequence caution

The sequence AAM65054.1 differs from that shown. Reason: Erroneous initiation.

The sequence CAB45785.1 differs from that shown. Reason: Erroneous gene model prediction. The predicted gene At4g01020 has been split into 2 genes: At4g01020 and At4g01026.

The sequence CAB80911.1 differs from that shown. Reason: Erroneous gene model prediction. The predicted gene At4g01020 has been split into 2 genes: At4g01020 and At4g01026.
