IFT81

Intraflagellar transport protein 81 homolog is a protein that in humans is encoded by the IFT81 gene. Together with IFT74/72 it forms a core complex to build IFT particles which are required for cilium formation. Additionally, it interacts with basal body components as CEP170 which regulates the disassembly of the cilium.
