WebDefinition Responds to a phosphorelay sensor to initiate a change in cell state or activity. The activity of the response regulator is regulated by transfer of a phosphate from a histidine residue in the sensor, to an aspartate residue in the response regulator. WebMar 1, 2001 · 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).

WebFeb 17, 2024 · ARR4 action on phyB and ARR4-controlled regulation of photomorphogenesis is dependent on its conserved phosphorylatable Asp 95, and this ARR4-mediated stabilization of phyB is reversed in the presence of cytokinins, providing a direct functional link between MSP and light signaling ( Mira-Rodado et al., 2007 ). Webgroup from a sensor kinase to a response regulator in the nucleus. The typical response regulators are classified into either type A or B. The type-B ARRs are transcription activators that act as positive regulators of cytokinin signaling, whereas most of the type-A ARRs are negative regulators of cytokinin signaling.
