persistence of hyaloid vascular system

Subcellular localization

basal body, cilia, endosome

Functional category

  • Ciliary assembly/disassembly
  • Trafficking (BBSome, small GTPases, vesicular transport, ATPases)
  • Actin & cytoskeleton regulation
  • Cell migration & adhesion
  • Signaling (Hedgehog, GPCRs, ion channels)
  • Ciliary membrane

Function

Regulator of the endocytic recycling compartment (ERC), binds to Rabin8 and transport it to the centrosome where it activates Rab8 to assemble the ciliary membrane from the ciliary vesicle (20308558, 31204173, 22718902). Rabin8- Rab11a interaction and preciliary trafficking are promoted by PI3K and Akt inhibitors (31204173).
