General Information
Term ciliary cap ID (Ontology) GO:0061822 (Gene Ontology)
Definition An intracellular compartmentalized cilium structure found in insect spermatids which is bounded by a membrane derived from the invagination of the cell membrane that remains associated with the primary cilium as it is internalized. The ciliary cap is maintained at the end of the axoneme distal to the centriole and is separated from the cytosolic axoneme/cytoplasm by a putative transition zone, which may extend into the ciliary cap, and include a structure at the base of the ciliary cap termed the ring centriole.[ PubMed:25447994 PubMed:27646273 ]
Also Known As "spermatid ciliary cap"
