Based on studies in mice, HIVEP3 (also known as SHN3 or Schnurri-3), a zinc finger adapter protein, binds to RUNX2 together with the E3 ubiquitin ligase WWP1. Hivep3 knockout mice exhibit increased bone mass, due to increased bone formation by osteoblasts, which is accompanied by increased expression of Runx2 target genes (Jones et al. 2006).
