VCP/p97-binding protein required for ciliogenesis . Acts as a tethering factor that facilitates recruitment of VCP/p97 to the intraflagellar transport complex B (IFT-B) in cilia . UBX domain-containing proteins act as tethering factors for VCP/p97 and may specify substrate specificity of VCP/p97 .
Subcellular locations: Cell projection, Cilium
Recruited to cilia in a VCP-dependent manner.
