Itf52 is part the IFT-B complex, which is involved in intraflagellar transport (IFT), the bidirectional movement of particles required for the assembly, maintenance and functioning of primary cilia. This entry represents the C-terminal domain of Itf52, responsible for the binding to the C-terminal domain of Ift46 and essential for the interaction between the subcomplexes. It shows an all-alpha structure [1,2].

Crystal structure analysis revealed that IFT81-N adopts the fold of a calponin homology (CH) domain with structural similarity to the kinetochore complex component NDC80 with microtubule (MT)-binding properties. Functional analysis show that IFT74 and IFT81 form a tubulin-binding module required for ciliogenesis. It is suggested that IFT81-N binds the globular domain of tubulin to provide specificity, and IFT74-N recognizes the beta-tubulin tail to increase affinity [1].
