Cellular component

Inv compartment of the cilium, cilial inversin compartment, cilium inversin compartment, flagellar inversin compartment, flagellum inversin compartment

Proximal part of the ciliary shaft to which the inversin protein (also called Inv) specifically localizes. The inversin compartment appears to have a different protein composition than the rest of the cilium, although there is no structure that separates it form the distal part of the cilium.

Note that cilia and eukaryotic flagella are deemed to be equivalent.
