Depositor Comments

Bidirectional vector expresses WRN and GFP at similar expression levels. In the associated article, cells were transiently transfected with this plasmid together with a tTA transactivator plasmid (Gossen, 1992).

This is a mammalian expression vector for catalytically active human WRN protein. lt was constructed from pBI, a Clontech plasmid with a bi-directional promoter+ TRE backbone, modified by insertion of a polylinker containing BspD1 and Xhol sites followed by insertion of myc-WRN WT. Vector backbone is pMM286, myc-WRN WT came from DspD1-Xhol fragment from pMM229.

The WRN sequence in this plasmid contains a number of variations from the WTWRN sequence (NM_000553.4). These polymorphisms are either silent or do not to alter the function of the WRN protein. *The A>G nucleotide change at position 235 was introduced into the WRN sequence during the cloning to generate myc epitope-tagged WRN. The subsequent amino acid change (S2G) does not appear to have any functional consequence on the WRN problem.
