== Function Summary ==
* **Entrez Summary**: This gene encodes a member of TTC21 family, containing several tetratricopeptide repeat (TPR) domains. This protein is localized to the cilium axoneme, and may play a role in retrograde intraflagellar transport in cilia. Mutations in this gene are associated with various ciliopathies, nephronophthisis 12, and asphyxiating thoracic dystrophy 4. [provided by RefSeq, Oct 2011].
* **UniProt Summary**: Component of the IFT complex A (IFT-A), a complex required for retrograde ciliary transport. Negatively modulates the SHH signal transduction (By similarity). {ECO:0000250}.
