MedKoo CAT#: 406434

CAS#: 719277-26-6

Description: TG003 is a potent, ATP-competitive inhibitor of Clk-family kinases (IC50 values are 20, 200 and 15 nM for mClk1, 2 and 4 respectively and >10 μ M for mClk3). . TG003 inhibited SF2/ASF-dependent splicing of beta-globin pre-mRNA in vitro by suppression of Clk-mediated phosphorylation. TG003 also suppressed serine/arginine-rich protein phosphorylation, dissociation of nuclear speckles, and Clk1/Sty-dependent alternative splicing in mammalian cells. Consistently, administration of TG003 rescued the embryonic defects induced by excessive Clk activity in Xenopus.
