Ts- pph22 mutant cells also accumulated aberrant microtubule structures at 37 degrees, while under semi-permissive conditions they were sensitive to the microtubule-destabilizing agent benomyl, suggesting that PP2A is required for normal microtubule function.

These results demonstrate that the regulation of PP2A, mediated by PR55/B binding to the highly conserved PP2Ac C-terminus, is critical for cell viability under conditions of microtubule damage and support a role for PP2A in exit from mitosis.
