sentences:  Intraflagellar transport, which is required for primary cilium assembly and maintenance, is driven by kinesin-2 motor made up of subunits KIF3A and KIF3B.Researchers have shown that FLCN could interact with both subunits in a cilium-dependent manner and localize to cilia in FLCN-expressing but not FLCN-deficient cells.Cilia have been shown to act as flow sensors and suppress mTOR signaling by activating the serine/threonine kinase LKB1 located in the basal body of resting cells in response to flow stimuli.
