Nup358 regulatory sequences drive expression of a fusion protein that is composed of the coding sequence for the Nup358 A isoform (a 69bp sequence that is only present in the B isoform has been deleted from the coding sequence) fused to a portion of RanGAP with a truncation of the C-terminal regulatory domain. In addition, the RanGAP coding sequence has been mutated to carry a R87A amino acid substitution, resulting in it being catalytically inactive.
