Fig. 5. Far1p-Ste5p interactions. Summary of potential related functional and physical interactions for both proteins, showing the fact that Far1p, Ste5p and Cdc24p all shuttle through the nucleus with the nuclear pool able to translocate to the cell periphery. Here it is pointed out that Far1p is a Fus3p substrate and that Ste5p could potentially target Cdc24p through its own interactions with Bem1p. See text for details.
