FRAP kinetics of wild-type and breakpoint MMSET variants. FRAP recovery curves from nucleoplasmic bleaching experiments of C-terminally tagged MMSET II/MB4-1 II (□), MB4-2 II (⋄), and MB4-3 II (○). Error bars represent the standard deviation. Only the initial recovery of MMSET II is represented as the x-axis has been shortened to allow the differences in the t_1/2 times to be more evident.
