• Reproduction & sperm
• Signaling (Hedgehog, GPCRs, ion channels)

Function

Modulates the Hedgehog (Hh) signalling pathway and is essential for ciliogenesis. It may be required for cilia extension and growth. Interacts with ciliary components involved in human ciliopathies such as BBSomes and IFT proteins. Shuttles between cilium and nucleus in response to Shh signalling. Implicated in congenital hypogo dotropic hypogo dism (CHH) and Kallmann syndrome (KS), characterised by delayed puberty and infertility (29263200).
