描述 The Clk (Cdc2-like kinase) family, consisting of at least four members, has been implicated in regulating alternative splicing by phosphorylation of SR (serine/arginine-rich) proteins. TG003 is a potent and ATP-competitive inhibitor of Clk with IC50s of 15, 20, 200 nM for mClK4, mClK1 and mClK2, respectively. TG003 (1 μM; 4 h) inhibited SF2/ASF-dependent splicing in HeLa cytosolic S100 extract by suppression of Clk1/Sty-mediated phosphorylation. It attenuated the splicing of β-globin pre-mRNA in S100 extract complemented with rSF2/ASF. When treated with 10 μM TG003 for 12 hours, HA-Clk1/Sty was localized in nuclear speckles in HA-Clk1/Sty-overexpressing HeLa cells with suppressed phosphorylation of SR proteins. In vivo, the abnormal development phenotype of the Xenopus embryos was rescued when they were incubated with 10 μM TG003[2].
