The kinesin-related protein, Costal2 (COS), forms a microtubule-associated 'scaffold complex' with Cubitus Interruptus (CI) and the Ser/Thr protein kinase Fused (FU). CI also associates directly with the Supressor of Fused (SU(FU)) protein in a separate complex. Complexes containing CI, COS, FU and SU(FU) are detectable but rare. The Ser/Thr protein kinases: Protein kinase A (PKA-C1), Shaggy (SGG), Casein kinase I alpha (CKIalpha), and Casein kinase I epsilon (DCO) all bind to the scaffold protein COS.
