UBCv1 functions as an E2 conjugating enzyme. (A) Analysis of the interaction between UBCv1/UBCv1C85A and ubiquitin in an ubiquitylation assay. (B) Representative images of the immunoprecipitation of HEK293 co-expressing Flag-UBCv1 plasmid or (C) Flag-UBCv1C85A and one of the following HA-Ub variations: HA-UbK48, HA-UbK63, HA-UbK48R, or HAUb-K63R. Spliced and grouped images from blots in boxes in (A–C) are shown in full in Supplementary Figure S1. Western blotting against HA and Flag tags was used for detection and whole-cell lysates (WCL) were loaded as transfection rate controls.
