Description: ML167 is the first highly selective inhibitor of of Cdc2-like kinase 4 (Clk4) with an IC50 of 136 nM for Clk4. The Cdc2-like kinases (ClkÂ’s) and the dual-specificity tyrosine phosphorylation-regulated kinases (DyrkÂ’s) have specified roles in gene splicing. Specifically, the Clk class of enzymes has been shown to phosphorylate the serine- and arginine-rich (SR) proteins, which are a major component of the spliceosome.
