Subcellular localization

cilia associated gene

Functional category

  • Ciliary assembly/disassembly
  • Trafficking (BBSome, small GTPases, vesicular transport, ATPases)
  • Actin & cytoskeleton regulation
  • Cell migration & adhesion

Function

Localizes to the trans-Golgi network (TGN) and recycling endosomes (RE) in polarized epithelial cells. Required for TGN identity and proper trafficking of proteins through the TGN → RE → plasma membrane pathway. Disruption of Rab13 (knockdown or mutants) impairs trafficking via this route, which is relevant for ciliary protein sorting, as many ciliary proteins pass through similar pathways(PMID: 18779367).

Model organism evidence

C. elegans (2 references)

Finally, genetic analyses reveal that the ciliary membrane expansions in dynamin and AP-2 mutants require bbs-8 and rab-8 function and that sensory signaling and endocytic genes may function in a common pathway to regulate ciliary membrane volume.
