摘要: Neural cell adhesion molecule (NCAM) associates with fibroblast growth factor (FGF) receptor-1 (FGFR1). However, the biological significance of this interaction remains largely elusive. In study, we show that NCAM induces a specific, FGFR1-mediated cellular response is remarkably different from elicited by FGF-2. contrast to FGF-induced degradation endocytic FGFR1, promotes stabilization receptor, which recycled surface in Rab11- and Src-dependent manner. turn, FGFR1 recycling required for NCAM-induced sustained activation various effectors. Furthermore, NCAM, but not FGF-2, migration, depends on Src activation. Our results implicate as nonconventional ligand exerts peculiar control intracellular trafficking resulting specific response. Besides introducing further level complexity regulation function, our findings highlight link FGFR signaling migration critical role these events dictating evoked receptor
