(A) The Mog1E65K Ran-binding mutant complements the slow growth of mog1ΔsetΔ mutants. Ten-fold serial dilutions of wild-type (WT), mog1Δ, set1Δ, and mog1ΔsetΔ strains transformed with wild-type MOG1 (pMOG1) or with the Ran-binding mutant (pMOG1E65K) as indicated were spotted on SC-LEU and incubated for 2 days at the indicated temperatures.
