Polyubiquitinated RUNX2 is degraded by the proteasome. As it has not been examined whether SCF(SKP2)-mediated polyubiquitination of RUNX2 leads to translocation of PolyUb-RUNX2 to the cytosol (Thacker et al. 2016), proteasome mediated degradation is assumed to happen in the nucleus. This process is inhibited by glucose uptake in osteoblasts (Wei et al. 2015).
