Kenny is modified by mixed K63-Ub and M1-Ub chains. a Drosophila S2 cells were transfected with empty vector, HA-tagged Kenny and V5-tagged wild-type LUBEL RBR-LDD. HA immunoprecipitations were performed at denaturing conditions and the samples were subjected to ubiquitin chain restriction (UbiCRest) with OTULIN and vOTU. Samples were analysed by Western blotting with α-M1, α-K63 and α-HA antibodies, n = 2. b Drosophila S2 cells were transfected with DIAP2, His-tagged K63-only Ub and V5-tagged Kenny. His-Ub pulldowns were performed at denaturing conditions and the samples were analysed by Western blotting with α-V5, α-DIAP2 and α-Actin antibodies, n = 3. c Drosophila S2 cells were transfected with empty vector, DIAP2, V5-tagged wild-type or C2704A LUBEL RBR-LDD, and HA-tagged Kenny. HA immunoprecipitations were performed at denaturing conditions and the samples were analysed by Western blotting with α-M1, α-K63, α-V5, α-HA, α-DIAP2 and α-Actin antibodies, n = 3. d Drosophila S2 cells were transfected with empty vector, HA-tagged Kenny and V5-tagged wild-type LUBEL RBR-LDD. M1-Ub chains were isolated from cell lysates with GST-NEMO-UBAN at denaturing conditions and the samples were subjected to UbiCRest with OTULIN and AMSH. Samples were analysed by Western blotting with α-M1 and α-HA antibodies, n = 3
