Function

Cilia protein required for cilia formation. Key regulator of hedgehog sig ling and as an intraflagellar transport B complex protein involved in anterograde and retrograde cilia transport. Deletion of Cluap1 causes a total loss of cilia within the developing embryo in mice (23351563, 31554018, 23742838). Role in cilia assembly and mainte nce, intracellular transport processes and cytoskeletal rearrangement by its interactions with TRIP6, which is suggested to be an actin and migration- modulating factor (29615496 )
