Protein
Putative two-component response regulator ARR13
Organism
Arabidopsis thaliana
Function
Putative transcriptional activator that binds specifically to the DNA sequence 5'-[AG]GATT-3'. 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. Could directly activate some type-A response regulators in response to cytokinins (By similarity).
Similarity
Belongs to the ARR family. Type-B subfamily.
