Signal Transduction Proteins Background

Signal transduction is a group of basic and important processes in molecular cell biology to deliver a signal from outside the cell to inside and reduce a functional change within the cell.

Signal transduction initiates with activation of a specific receptor located on the cell surface or inside the cell by extracellular signaling molecule. Then the active receptor leads a biochemical chain of events inside the cell to respond. Finally, changes about metabolism, shape, gene expression, or ability to divide are triggered depending on the cell type. During the delivery process, signal can be amplified at any step so that one signal molecule can reduce many responses.

Signal transduction systems help coordinate the activities of hundreds to trillions of cells in multicellular organisms. In multicellular organisms, there are a variety of mechanisms for cell-to-cell communication. For example, our skin grows at the right rate to replace loss of its surface every day of our lives. This accurate regulation exists in every tissue of our body, and once this fine regulation breaks down, cancer may occur. All these cannot realize without signal transduction.

As a primary manufacturer of recombinant proteins, Creative Biomart provides signal transduction molecules of several sources, grades and formulations for research applications.
