Protein Modules as Coupling Elements of Signal Proteins

2 Protein Modules as Coupling Elements of Signal Proteins 

Starting from an activated receptor tyrosine kinase, further conduction of the signal takes place with the help of specific protein-protein interactions between the activated receptor and one or more effector proteins next in the sequence. In many cases, the effector molecules pass the signal on to other proteins of the signaling pathway, forming chains of signal proteins in sequence. Specific protein-protein interactions are the 

At present, a number of structural motifs have been described for signal proteins, to which specific coupling fimctions in signal transduction are attributed. The most important are
