Involved in several processes, including cilium organization; embryonic morphogenesis; and protein localization to organelle. Acts upstream of or within several processes, including embryonic morphogenesis; non-motile cilium assembly; and smoothened signaling pathway. Located in several cellular components, including ciliary basal body; ciliary base; and photoreceptor connecting cilium. Part of intraciliary transport particle A. Is expressed in choroid plexus; dorsal root ganglion; genitourinary system; olfactory epithelium; and pituitary gland. Human ortholog(s) of this gene implicated in cranioectodermal dysplasia 1. Orthologous to human IFT122 (intraflagellar transport 122). [provided by Alliance of Genome Resources, Apr 2022]
