The original version of this Article contained an error in the accession codes section, which specified an accession code for an unrelated protein. The correct PDB accession code for structural coordinates of the N-terminal domain of Fsp27 is 4IKG. This has now been corrected in both the PDF and HTML versions of the Article.
