Protein
Two-component response regulator ARR9
Organism
Arabidopsis thaliana
Function
Functions as response regulator involved in His-to-Asp phosphorelay signal transduction system. Phosphorylation of the Asp residue in the receiver domain activates the ability of the protein to promote the transcription of target genes. Type-A response regulators seem to act as negative regulators of the cytokinin signaling.
Similarity
Belongs to the ARR family. Type-A subfamily.
