Functional category

• Ciliary assembly/disassembly
• Trafficking (BBSome, small GTPases, vesicular transport, ATPases)
• Actin & cytoskeleton regulation
• Protein processing & maturation
• Signaling (Hedgehog, GPCRs, ion channels)
• Cardiac & muscle development
• Transition zone
• Transcription regulation

Function

Also known as p27Kip1. Multifunctional protein that plays crucial roles in cell architecture and migration by regulating rearrangements of the actin cytoskeleton and . p27Kip1 abrogation impairs one of the earliest events of ciliogenesis, docking of the Ehd1- associated preciliary vesicles to the distal appendages of the basal body (32423824).
