SMURF1 and SMURF2 polyubiquitinate RUNX3 on unknown lysine residues, possibly K148, K186 and K192, targeting it for degradation. The interaction between SMURFs and RUNX3 involves the PY motif of RUNX3 and the WW domain of SMURFs. Acetylation of RUNX3 by EP300 (p300) prevents SMURF-mediated ubiquitination of RUNX3, thus increasing RUNX3 protein stability (Jin et al. 2004).
