Signalling

 Signaling is considered as the transfer of data.  cell signaling occurs when an extracellular signaling particle starts the particular receptor that is found on the surface of the cell r inside the cell. When the signal is received, the receptor triggers a biochemical chain inside the cell. This is considered as a response given by the cell. There are numerous cells and depending on each cell the reaction changes accordingly. The reaction modifies on the cell can be of gene expression, change in shape, cell metabolism, and ability to separate. The signaling comprises the molecular aspects of cell signaling without receptors, phosphatases, transcription factors, G-proteins, and kinases. The transcription factors include the regulation in the cell apoptosis, differentiation, proliferation, and oncogenesis in the mammalian cells.
