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 .
Subcellular locations: Cytoplasm, Cytoskeleton, Cell projection, Cilium
Associated with microtubules . Localized at the distal tip of the cilium .
Expressed in the retina, predominantly in the photoreceptor outer segment.
