FIGURE 3

SRSF2 mutants promote exon 9.5 of EZH2 gene through binding to CCWG motif. (A) Sequence logos for the motifs enriched in inclusion-type exons with WT, P95H, P95L, and P95R are presented. (B) Sequence logos for the motifs enriched in inclusion-type exons with WT, P95H, P95L, and P95R are shown. (C) Sequence of exon 9.5 (pseudo exon) in human EZH2 gene. In frame stop codons are underlined. CCWG motif, found with SRSF2 P95H and P95R proteins in (B), are indicated with open boxes. (D) Splicing pattern of EZH2 pre-mRNA in myc-vector, SRSF2 WT, P95H, P95L, and P95R are indicated. The ratio of exon9.5 included product in total splicing products is shown beneath the panel. The schematic representations of PCR products are shown at the right side of the panel. RT, Reverse Transcriptase. M, DNA size marker.
