Alternative splicing of the primary Sty (another name for CDC-like kinase 1 (CLK1)) transcript generates mRNAs encoding full-length catalytically active (STY) and truncated (via skipping of cassette exon HsaEX0015695), kinase-deficient polypeptides. Both STY and its truncated isoform, STYT, are localized in the nucleus and are capable of heterodimerizing.

The Clk1 kinase, which phosphorylates SR proteins, is regulated through alternative splicing of the Clk1 pre-mRNA, yielding mRNAs encoding catalytically active (includes cassette exon HsaEX0015695) and truncated inactive polypeptides (skips HsaEX0015695) (Clk1 and Clk1T , respectively). The authors present evidence that Clk1 and Clk1T proteins regulate the splicing of Clk1 and adenovirus pre-mRNAs in vivo. The peptide domain encoded by the alternatively spliced exon of Clk1 is essential for the regulatory activity of the Clk1 kinase. This is the first direct demonstration of an in vivo link between alternative splicing and protein kinase activity. (Seems to be a case of auto-regulation of ratio of Clk1 transcripts with/without the cassette exon)
