Dual specificity protein kinase TTK kinase domain complex with inhibitor, 2x9e Show:Asymmetric Unit Biological Assembly Drag the structure with the mouse to rotate   Export Animated Image Function Dual specificity protein kinases are kinases which act as both tyrosine kinase and serine/threonine kinase. CLK1 phosphorylates serine/arginine-rich proteins involved in pre-mRNA processing. Clk2 and Clk3 cause the redistribution of SR proteins and can regulate the alternative splicing of precursor mRNA[1]. Structural highlights The dual specificity protein kinase TTK or monopolar spindle kinase 1 contains tetratricopeptide repeat domain (TPR) which serves as interaction domain between proteins. The TPR domain is a helical 34 amino acid motif which is found in several copies in a protein which fold together forming a protein-protein binding domain.
