Regulates cubitus interruptus (ci) processing by recruiting multiple kinases to promote its efficient phosphorylation. Scaffolds multiple kinases and ci into proximity to promote its hyperphosphorylation, which then targets it for SCFSlimb/proteasome-mediated processing to generate its repressor form. Hh signaling inhibits ci phosphorylation by interfering with the cos-ci-kinases complex formation (By similarity). Homodimer (Potential). Binds microtubules. Interacts with ci, smo, sgg, CkIalpha and protein kinase A catalytic subunit (By similarity). Belongs to the TRAFAC class myosin-kinesin ATPase superfamily. Kinesin family. KIF27 subfamily.
