- A cytokinin signaling and response regulator protein is a plant protein that is involved in a two step cytokinin signaling and response regulation pathway. The current model of cytokinin signaling and response regulation shows that it works as a multi-step phosphorelay two-component signaling system. This type of system is similar to two-component signaling systems in bacteria. The cytokinin signaling pathway consists of sensor kinases, histidine phosphotransfer proteins, and response regulators. In this system, cytokinin sensor kinases are activated by the presence of cytokinins. The sensor kinase then autophosphorylates, transferring a phosphate from its kinase domain to its receiver domain. The phosphate is then transferred to a histidine phosphotransfer protein which then phosphorylates a response regulator. The response regulators can then serve as positive or negative regulators of the signaling mechanism and affect gene expression within the plant cells. This system is a called a two-step system because it involves two steps to transfer the phosphate to the final target, the response regulators.Cytokinin cause a rapid increase in the expression of response regulator genesCytokinins are a class of phytohormones that promote cell division in plants. Cytokinins participate in short and long-distance signaling and are transported for this signaling through the xylem of plants. Cytokinins control the differentiation of meristem cells in plant development, particularly in shoots and roots where plants undergo growth. Cytokinins act in a restricted region of the root meristem, and their signaling and regulation of genes occurs through a multi-step phosphorelay mediate by cytokinin histidine sensor kinases, histidine phosphotransfer proteins, and cytokinin response regulator proteins.
