comment
  • 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. {ECO:0000250|UniProtKB:Q9ZWS9}.
  • TISSUE SPECIFICITY: Expressed in roots, leaf blades, leaf sheaths, shoot apex, flowers and panicles. {ECO:0000269|PubMed:16919402}.
  • INDUCTION: By cytokinin in roots and shoots. {ECO:0000269|PubMed:22383541}.
  • PTM: Two-component system major event consists of a His-to-Asp phosphorelay between a sensor histidine kinase (HK) and a response regulator (RR). In plants, the His-to-Asp phosphorelay involves an additional intermediate named Histidine-containing phosphotransfer protein (HPt). This multistep phosphorelay consists of a His-Asp- His-Asp sequential transfer of a phosphate group between first an His and an Asp of the HK protein, followed by the transfer to a conserved His of the HPt protein and finally the transfer to an Asp in the receiver domain of the RR protein. {ECO:0000305}.
  • DISRUPTION PHENOTYPE: Dwarf, albino, lesion mimic and low fertility phenotypes. {ECO:0000269|PubMed:16891544}.
  • SIMILARITY: Belongs to the ARR family. Type-A subfamily. {ECO:0000305}.
