(A) Isoform diagrams for the genes CCNE2, NAB1, NAE1, NDC1, RICTOR, and SRSF5. Coding regions are wide boxes, noncoding regions are narrow boxes, introns are lines, and upstream open reading frames (uORFs) are indicated by gray bars. Differentially included regions are shown in yellow, arrows show the direction of transcription, and select introns have been removed for clarity as indicated by gaps. (B) Secondary structures of two RICTOR 5′ leader sequences predicted by RNAfold. RNA bases are colored by base pairing probability.
