Predicted to be involved in intraciliary retrograde transport and regulation of cilium assembly. Predicted to act upstream of or within several processes, including embryonic organ development; nervous system development; and non-motile cilium assembly. Predicted to be located in microtubule organizing center and photoreceptor cell cilium. Predicted to be part of intraciliary transport particle A. Predicted to be active in axoneme and ciliary basal body. Human ortholog(s) of this gene implicated in retinitis pigmentosa and short-rib thoracic dysplasia 9 with or without polydactyly. Orthologous to human IFT140 (intraflagellar transport 140). [provided by Alliance of Genome Resources, Apr 2022]
