TIRF imaging of CRISPR-edited human cells shows dynein–dynactin complexes move processively with motility parameters consistent with the presence of multi-dynein assemblies (>one dynein heavy chain dimer per dynactin) in cells.
Uev1A and APC/C degrade CycA to counteract oncogenic Ras, thereby protecting against cell death in polyploid Drosophila nurse cells and suppressing overgrowth in diploid germline and human colorectal tumor cells.
