... Docking proteins are recruited to the site of RTK activation at the plasma membrane, they reinforce binding by virtue of a receptor-binding domain (often a phosphotyro- sine-binding domain) and ... signaling proteins, these proteins direct the flow of information in the cell by activating, coordinating and regulating signaling events in regulatory networks. Here we discuss the catego...
