Interaction network analysis of proteins identified by LC-MS/MS. Phosphoproteins identified by LC-MS analysis are represented as grey nodes, the subset of proteins uniquely identified upon WKYMVm stimulation are indicated as green nodes, and selected phosphoproteins known to be involved in FPR2 stimulation by WKYMVm are shown as red nodes. The core molecule of the larger cluster within the network was found to converge on β-arrestin-1 (ARRB1). The network was constructed by including clusters with more than one node and excluding interactions from outside the selected dataset.
