Abstract
The first question that arises in the study of the molecular action mechanism of hormone signals, like auxins, will be the initial interaction of the signal within the cell. Cells can detect signals which they receive by means of receptor proteins. These proteins specifically and reversibly bind the signals without changing them chemically. Upon binding the receptors are, through a conformational change, transformed into an activated state, thus initiating a molecular programme that ultimately leads to the (signal-)characteristic response. Thus, receptor proteins act both as primary detectors and transducers of the hormonal signal.
