Updated project metadata. In this study we performed 2 interactomes. To identify interactants of RNF111 that are dependent of the RING domain, we performed qualitative interactome comparison of HEK-293 cells transfected with GFP, GFP-RNF111-wt or GFP-RNF11-C933A mutated in its RING domain. This led to the identification of UBXN7 as a RING-dependent partner for RNF111. To identify UBXN7 UAS dependant partners, we performed quantitative interactome comparison of HEK-293 cells transfected with GFP, GFP-UBXN7-UAS.
