In the above-mentioned article, Supplemental Figures 3 and 6 included several errors which have been corrected in Revised Supplemental Material online. The changes:
-
The legend presented with the original Supplemental Figure 3 was intended for a different figure and should instead read as follows:
Supplemental Figure 3: Multiple PDEs synergize in activating weak 5′ splice sites. To analyze the functional interdependence of the intrinsic strength of a 5′ss defined by its ability to basepair with the U1 snRNA and the sequence surrounding, we mutated the 5′splice site to gradually vary its strength (A) and tested it in the context of different numbers of enhancer binding sites in the vicinity. (B) Transfection experiments were carried out as described above and samples were subjected to semi-quantitative and quantitative RT-PCR analysis.
The axes in panel A in the original Supplemental Figure 6 were off by a factor of 10 (see Revised Supplemental, online).
The authors apologize for any confusion this may have caused.
