Application

TG003 has been used in PAC1 cell culture and in vitro kinase assays.
TG003 has been used to develop assays for screening substances that affect mRNA splicing1.

Biochem/physiol Actions

TG003 regulates alternative splicing and reduces the phosphorylation of SF2/ASF1.
TG003, a CLK (cdc2-like kinase) family inhibitor is used as a drug for duchenne muscular dystrophy.
