CC   -!- FUNCTION: Functions as response regulator involved in His-to-Asp
CC       phosphorelay signal transduction system. Phosphorylation of the Asp
CC       residue in the receiver domain activates the ability of the protein to
CC       promote the transcription of target genes. Type-A response regulators
CC       seem to act as negative regulators of the cytokinin signaling.
CC       {ECO:0000250|UniProtKB:Q9ZWS9}.
CC   -!- TISSUE SPECIFICITY: Expressed in roots, mature leaves and flowers, and
CC       at low levels in shoots. {ECO:0000269|PubMed:16472405}.
CC   -!- INDUCTION: Not induced by cytokinin. {ECO:0000269|PubMed:16472405}.
CC   -!- PTM: Two-component system major event consists of a His-to-Asp
CC       phosphorelay between a sensor histidine kinase (HK) and a response
CC       regulator (RR). In plants, the His-to-Asp phosphorelay involves an
CC       additional intermediate named Histidine-containing phosphotransfer
CC       protein (HPt). This multistep phosphorelay consists of a His-Asp-His-
CC       Asp sequential transfer of a phosphate group between first an His and
CC       an Asp of the HK protein, followed by the transfer to a conserved His
CC       of the HPt protein and finally the transfer to an Asp in the receiver
CC       domain of the RR protein. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the ARR family. Type-A subfamily. {ECO:0000305}.
