Intracellular trafficking of fibroblast growth factor 2 (FGF2) exhibits two unusual features: (i) it is secreted despite the lack of signal peptide and (ii) it can translocate to the nucleus after interaction with high- and low-affinity receptors on the cell surface, although it does not possess any classical nuclear localization signal. This nuclear translocation constitutes an important part of the response to the growth factor. Previously, we identified Translokin/CEP57, an FGF2 binding partner, as an intracellular mediator of FGF2 trafficking, which is essential for the nuclear translocation of the growth factor. Here, we report the identification of four Translokin partners: sorting nexin 6, Ran-binding protein M and the kinesins KIF3A and KIF3B. These proteins, through their interaction with Translokin, are involved in two exclusive complexes allowing the bidirectional trafficking of FGF2. Thus, Translokin plays a pivotal role in this original mechanism. In addition, we show that FGF2 secretion is regulated by a negative loop, retro-controlled by FGF receptor and involving FGF2 itself.
