Structural basis for the recognition of a nucleoporin FG-repeat by the NTF2-like domain of TAP-p15 mRNA export factor
Overview
TAP-p15 heterodimers have been implicated in the export of mRNAs through, nuclear pore complexes (NPCs). We report a structural analysis of the, interaction domains of TAP and p15 in a ternary complex with a Phe-Gly, (FG) repeat of an NPC component. The TAP-p15 heterodimer is structurally, similar to the homodimeric transport factor NTF2, but unlike NTF2, it is, incompatible with either homodimerization or Ran binding. The NTF2-like, heterodimer functions as a single structural unit in recognizing an FG, repeat at a hydrophobic pocket present only on TAP and not on p15. This FG, binding site interacts synergistically with a second site at the C, terminus of TAP to mediate mRNA transport through the pore. In general, our findings suggest that FG repeats bind with a similar conformation to, different classes of transport factors.
