Upon activation , intracellular domains of FPR2 mediate signaling to G - proteins , which trigger several agonist - dependent signal transduction pathways , including activation of phospholipase C ( PLC ) , protein kinase C ( PKC ) isoforms , the phosphoinositide 3 - kinase ( PI3K ) / protein kinase B ( Akt ) pathway , the mitogen - activated protein kinase ( MAPK ) pathway , p38MAPK , as well as the phosphorylation of cytosolic tyrosine kinases , tyrosine kinase receptor transactivation , phosphorylation and nuclear translocation of regulatory transcriptional factors , release of calcium and production of oxidants .
