SMURF2 ubiquitinates Smad7 and phosphorylated TGFBR1

When recombinant mouse Smad7 and recombinant human SMURF2, TGFBR2 and TGFBR1 are exogenously expressed in HEK293 cells, SMURF2 (recruited to the activated TGF-beta receptor complex through interaction with Smad7) ubiquitinates Smad7 and may also ubiquitinate TGFBR1. Experimental findings on ubiquitination of TGFBR1 by SMURF2 were inconclusive (Kavsak et al. 2000).
