General Information
Term ciliary basal body ID (Ontology) GO:0036064 (Gene Ontology)
Definition A membrane-tethered, short cylindrical array of microtubules and associated proteins found at the base of a eukaryotic cilium (also called flagellum) that is similar in structure to a centriole and derives from it. The cilium basal body is the site of assembly and remodeling of the cilium and serves as a nucleation site for axoneme growth. As well as anchoring the cilium, it is thought to provide a selective gateway regulating the entry of ciliary proteins and vesicles by intraflagellar transport.[ PubMed:21750193 ]
Also Known As "cilial basal body" ; "cilium basal body" ; "kinetosome" (for all, see Synonyms field below)
