CC   -!- FUNCTION: Transcriptional activator that binds specific DNA sequence.
CC       Functions as a response regulator involved in His-to-Asp phosphorelay
CC       signal transduction system. Phosphorylation of the Asp residue in the
CC       receiver domain activates the ability of the protein to promote the
CC       transcription of target genes. May directly activate some type-A
CC       response regulators in response to cytokinins.
CC       {ECO:0000250|UniProtKB:Q940D0}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00625}.
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-B subfamily. {ECO:0000305}.
