abstract = {Terminally differentiated cells can be reprogrammed to
pluripotency by the forced expression of Oct4, Sox2, Klf4
and c-Myc. However, it remains unknown how this leads to the
multitude of epigenetic changes observed during the
reprogramming process. Interestingly, Oct4 is the only
factor that cannot be replaced by other members of the same
family to induce pluripotency. To understand the unique role
of Oct4 in reprogramming, we determined the structure of its
POU domain bound to DNA. We show that the linker between the
two DNA-binding domains is structured as an α-helix and
exposed to the protein's surface, in contrast to the
unstructured linker of Oct1. Point mutations in this
α-helix alter or abolish the reprogramming activity of
Oct4, but do not affect its other fundamental properties. On
the basis of mass spectrometry studies of the interactome of
wild-type and mutant Oct4, we propose that the linker
functions as a protein-protein interaction interface and
plays a crucial role during reprogramming by recruiting key
epigenetic players to Oct4 target genes. Thus, we provide
molecular insights to explain how Oct4 contributes to the
reprogramming process.},
