As a component of IFT complex A (IFT-A), a complex required for retrograde ciliary transport and entry into cilia of G protein-coupled receptors (GPCRs), it is involved in ciliogenesis . Involved in retrograde ciliary transport along microtubules from the ciliary tip to the base .
Cytoplasm, cytoskeleton . Cell projection, cilium . Associated with microtubules (PubMed:22361696). Localized at the distal tip of the cilium (PubMed:28973684). .
