Functional category

  • Ciliary assembly/disassembly
  • Actin & cytoskeleton regulation
  • Neurogenesis & migration
  • Protein processing & maturation

Function

Binds to Ptc1 and inactivates it, leading to accumulation of Smo and activation of signaling. Primary cilia regulates its activity ( 17641202). Shh controls patterning and proliferation through the primary cilium ( 31825820).
