Figure S4. Auto-ubiquitination activity of full-length TRIM28 with a range of E2 conjugating enzymes.

Figure S4.

Upper panel: full-length TRIM28 was incubated with E1, ubiquitin, ubiquitinAtto, and a range of E2 enzymes as indicated. The reactions were monitored for auto-ubiquitination over 60 min. The TRIM25 RBCC was included in conjunction with UBE2D as a positive control. Lower panel: the results of the same assay carried out in the absence of any E3 ligase. The band labelled by an asterisk is likely an auto-ubiquitinated form of UBE2K.
