The E3 ubiquitin ligase RNF146 possesses a PAR recognition domain (WWE) which binds to PARylated PTEN. RNF146 polyubiquitinates PARylated PTEN, with lysine residues K342, K344 and K349 as major ubiquitination sites. RNF146-mediated ubiquitination targets PTEN for proteasome-mediated degradation (Li et al. 2015).
