Crosstalk (biology)

Crosstalk (biology)

Biological crosstalk refers to instances in which one or more components of one signal transduction pathway affect another. This can be achieved through a number of ways with the most common form being crosstalk between proteins of signaling cascades. In these signal transduction pathways, there are often shared components that can interact with either pathway. A more complex instance of crosstalk can be observed with transmembrane crosstalk between the extracellular matrix (ECM) and the cytoskeleton.
