Enables intraciliary transport particle B binding activity. Involved in cilium organization; protein localization to cilium; and smoothened signaling pathway. Acts upstream of or within manchette assembly. Located in centrosome and ciliary basal body. Part of intraciliary transport particle B. Orthologous to human TTC26 (tetratricopeptide repeat domain 26). [provided by Alliance of Genome Resources, Apr 2022]
