• Signal Transduction

    Posted on Dec 27, 2018

    Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation which results in a cellular response. Protein receptors detect stimuli from ligand agonists which trigger the process. At the molecular level, such responses include changes in the transcription or translation of genes, and post-translational and conformational changes in proteins, as well as changes in their location.
