NEM treatment of HeLa cellular lysates inhibits both RanGEF and RanGAP activity. Cellular lysates were prepared as described in the Materials and methods and treated with either (♦) 10, (▴) 20, (•) 40, or (▪) 60 mM NEM for the indicated period of time, quenched with excess DTT, and measured as follows: (A) measurement of RanGEF activity in HeLa cell extracts after NEM treatment; (B) measurement of RanGAP activity in HeLa cell extracts after NEM treatment. Both RanGAP and GEF activity were measured as described in the Materials and methods.
