Correction

After the publication of this work[1] it was brought to the authors’ attention that Figure three (Figure1 here) contained a duplication error, where the HP1gamma staining for wild-type thymus and brain are identical. The correct figure is given below.

Figure 1
figure 1

HP1γ protein expression was dramatically reduced in Cbx3hypo/hypotissues. Protein expression was reduced to almost undetectable levels in testis, kidney, lung, brain, liver spleen and thymus tissues from the Cbx3hypo/hypomice.
