SMA and insoluble LEN do not progress in folding. Transfected cells were treated with 10 μg/ml ALLN overnight. Soluble (S) and pelleted, insoluble (P) fractions were separated by SDS-PAGE under reducing (R) and nonreducing (NR) conditions and analyzed by Western blotting. Twofold more insoluble than soluble material was loaded. F0, completely reduced LC; Fox, LC containing two disulfide bonds. Only soluble LEN folds into the Fox state. All of SMA, insoluble LEN, and a small percentage of soluble LEN is found in the F0 state.
