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 -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- TISSUE SPECIFICITY: Predominantly expressed in roots and young flowers.
CC {ECO:0000269|PubMed:11115887, ECO:0000269|PubMed:9482949}.
CC -!- INDUCTION: By cytokinins (BA and zeatin) and nitrate.
CC {ECO:0000269|PubMed:11115887, ECO:0000269|PubMed:9662428}.
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.
CC -!- SIMILARITY: Belongs to the ARR family. Type-A subfamily. {ECO:0000305}.
