... 17 residues of 4E-BP1 contain the RAIP motif. To assess whether removal of the RAIP motif accounts for the reduced binding of raptor to the 18– 117 fragment, we compared the binding of raptor to this ... after treatment of cells with insulin [25]. Replacing its N-terminus with the N-terminal part of 4E-BP1 led to a marked increase in its phosphoryla- tion (even in...
