null Serves as a phospho-His intermediate enabling the transfer of phospho group between a hybrid kinase and a response regulator. Elemental activities, such as catalysis or binding, describing the actions of a gene product at the molecular level. A given gene product may exhibit one or more molecular functions. Interacting selectively and non-covalently and simultaneously with one or more signal transduction molecules, usually acting as a scaffold to bring these molecules into close proximity either using their own SH2/SH3 domains (e.g. Grb2) or those of their target molecules (e.g. SAM68). The molecular function that accepts an input of one form and creates an output of a different form. Combining with an extracellular or intracellular messenger to initiate a change in cell activity. Alters the level of transcription of target genes, usually by binding to a transcription factor, when phosphorylated by a sensor that detects the presence of a particular signal substance outside the cell. null null Mediates the transfer of a signal from the outside to the inside of a cell by means other than the introduction of the signal molecule itself into the cell. null Catalysis of the phosphorylation of a specific transcription regulator in response to the presence of a particular signal substance outside the cell.
