Deltex and RING-UIM E3 ligases cooperate to create a ubiquitin-ADP-ribose hybrid mark on tankyrase, promoting its stabilization
Jérôme Perrard, Kevin Gao, Katherine Ring, Susan Harless Smith
The paper identifies a mechanism where Deltex E3 ligases modify tankyrase with a ubiquitin-MAR hybrid mark, preventing PAR formation and stabilizing tankyrase through interaction with RNF114 and RNF166.
