Function
Regulates cilium length and morphology, ciliary and preciliary membrane volume. Interacts with RABS-5 to control periciliary vesicle number, levels of polycystin- 2, fusion and maturation of specific cilium-derived endocytic vesicles and early endosomes (29572244).
Model organism evidence
C. elegans (1 reference)
Here, using Caenorhabditis elegans, we describe closely linked functions for early endosome (EE) maturation factors RABS-5 (Rabenosyn-5) and VPS-45 (VPS45) in regulating cilium length and morphology, ciliary and periciliary membrane volume, and ciliary signalling-related sensory behaviour.
