Tls1 regulates the proper splicing of shelterin components. (A) List of number of introns present in the genes of telomere proteins. (B) RT-PCR analyses of RNA with primers flanking introns. Genomic DNA (gDNA) was used in a control PCR reaction to indicate the position of unspliced form. The structures of the genes are indicated on top and boxes represent exons. The primer positions were labeled. (C) qRT-PCR analyses of intron retention levels, normalized to act1. Wild-type levels were set to 1. Bars represent PCR fragment amplified. (D) Western blot analyses of shelterin protein levels. Ponceau S staining was used as the loading control. (E) Live cell imaging of cells expressing GFP-tagged versions of shelterin. Scale bar, 1 μm.
