Functions in protein sorting and gating (i.e. active and passive transport of proteins in and out of the cilium). In mammals, ciliary transition fibers comprise at least five components (Ccdc41/Cep83, Cep89/Cep123, Sclt1, Fbf1, and Cep164) (PMID:24469809). centriolar distal appendage cellular_component distal appendage of centriole GO:0097539 distal appendage of basal body cilium transition fiber distal appendage of mother centriole intracellular protein-containing complex
