Intraflagellar transport protein 81 (IPR029600)

Short name: IFT81

Overlapping homologous superfamilies


Family relationships



Intraflagellar transport of ciliary precursors such as tubulin from the cytoplasm to the ciliary tip is required for ciliogenesis [PMID: 12415299]. Intraflagellar transport protein 81 (IFT81) is a component of the intraflagellar transport (IFT) complex B, which contains at least 20 different protein subunits. Together with IFT74 forms a tubulin-binding module that specifically mediates transport of tubulin within the cilium [PMID: 23990561].
