Modulates cilium assembly. ATP + L-seryl-[protein] = ADP + H(+) + O-phospho-L-seryl-[protein] ATP + L-threonyl-[protein] = ADP + H(+) + O-phospho-L-threonyl-[protein] Localizes to the ciliary transitional zone in head and tail neurons. Specifically expressed in head and tail ciliated sensory neurons. Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
