signal transduction
Noun
Meaning
signal transduction (uncountable)
(biochemistry) A series of chemical reactions within a cell which start when a transmembrane protein comes into contact with a chemical signal, resulting in a second messenger being triggered.
Examples
Signal transduction The active tyrosine kinase phosphorylates specific target proteins, which are often enzymes themselves.
Signal transduction Integrins play an important role in cell signaling by modulating the cell signaling pathways of transmembrane protein kinases such as receptor tyrosine kinases (RTK).
Signal transduction occurs when an extracellular signaling http://www.ncbi.nlm.nih.gov/books/NBK21517 molecule activates a specific receptor located on the cell surface or inside the cell.
