Biochem. J. (2005) 385(1), 45–56

A reader has contacted the Biochemical Journal Editorial Board to draw attention to a potential concern regarding some of the data Figures in this article. The concerns raised are regarding band similarities in Figure 2B and evidence of gel splicing in this figure, Figure 4, and others. Due to the time elapsed between publication of the article and the concerns being raised, as well as the recent passing of the senior author, Lady Tricia Cohen, it will not be possible to conduct an investigation and source the original data to verify or allay the concerns raised. Following COPE guidance, the Editorial Board has therefore decided to issue an Expression of Concern to alert readers to this issue. The authors have been informed of this notification.
