The subsets of SH2- and PTB-binding signaling molecules recruited to an activated receptor are defined by the pattern of phosphorylated tyrosine residues in the C-terminus of the receptor ( Figure 3 ). ErbB family members are utilised by pathogens attempting to gain cellular entry, subvert immune responses, and manipulate the cell cycle of infected host cells. These events support and are necessary for pathogen persistence.
