Figure 1From: Alternative trans-splicing of Caenorhabditis elegans sma-9/schnurri generates a short transcript that provides tissue-specific function in BMP signalingStructure of sma-9 transcript variants. The predicted sma-9 intron-exon structure is shown above. Arrows mark positions of nonsense codons in three sma-9 alleles. pCS386 is the most complete cDNA variant isolated to date. The two short variants represented by cDNA clones yk1285a11 (A11) and yk1237d01 (D01) are shown below. ARD: acidic residue-rich domain; NLS: nuclear localization signal.Back to article page
