Intraflagellar transport protein 81 homolog is a protein that in humans is encoded by the IFT81 gene.^[1][2] Together with IFT74/72 it forms a core complex to build IFT particles^[3] which are required for cilium formation. Additionally, it interacts with basal body components as CEP170^[4] which regulates the disassembly of the cilium.
