英文摘要The adaptor protein paxillin plays an important role in cell migration. although the c-jun amino-terminal kinase (jnk) phosphorylation of paxillin on ser 178 has been found to be critical for cell migration, the precise mechanism by which jnk regulates cell migration is still not very clear. here, the migration of human corneal epithelial (hce) cells was used to determine which signaling pathways are involved in egf-induced paxillin phosphorylation. paxillin was phosphorylated on tyr 31 and tyr 118 after induction of migration by egf in hce cells. specific inhibition of jnk activation by inhibitor sp600125 or overexpression of a dominant-negative jnk mutant not only blocked egf-induced cell migration, but also eliminated tyrosine phosphorylation of paxillin on tyr 31 and tyr 118. hce cells overexpressing paxillin-s178a mutant also exhibited lower mobility, and reduced phosphorylation of tyr 31 and tyr 118. however, paxillin-s178a-inhibited cell migration can be rescued by overexpression of paxillin-y31e/y118e mutant. importantly, inhibition of jnk by sp600125 or overexpression of paxillin-s178a mutant prevented the association of fak with paxillin. taken together, these results suggest that phosphorylation of paxillin on ser 178 by jnk is required for the association of paxillin with fak, and subsequent tyrosine phosphorylation of paxillin.
