This figure shows a model explaining the distal activation of integrins by uPAR. The binding of SRSRY sequence of uPAR to formyl peptide receptors such as FPRL1 (thick blue arrow) or the binding of D2A sequence located in domain 2 of uPAR to integrins (thick red arrow) initiates outside-in signalling converging towards phosphorylated moesin (P-moesin) and merlin (thin blue and thin red arrows), which results in the de-phosphorylation of moesin and phosphorylation of merlin (thick black arrow). This latter step initiates inside-out signalling (thick purple arrow) activating distal integrins (yellow arrow) that are involved in cell adhesion and migration (green arrow).
