General Information
Term ciliary transition fiber ID (Ontology) GO:0097539 (Gene Ontology)
Definition A nine-bladed, propeller-like protein complex that links the distal end of the basal body and the cilium to the plasma membrane. Functions in protein sorting and gating (i.e. active and passive transport of proteins in and out of the cilium).[ PubMed:22653444 PubMed:24231678 PubMed:5064817 PubMed:5335827 ]
Also Known As"cilial transition fiber" ; "cilial transition fibre" ; "ciliary transition fibre" (for all, see Synonyms field below)
