Predicted to be involved in cilium organization; protein localization to ciliary membrane; and protein-containing complex assembly. Predicted to act upstream of or within several processes, including embryonic organ development; myotome development; and smoothened signaling pathway. Predicted to be located in motile cilium and photoreceptor connecting cilium. Predicted to be part of intraciliary transport particle A. Predicted to be active in cilium. Human ortholog(s) of this gene implicated in several diseases, including Caroli disease; Senior-Loken syndrome; asphyxiating thoracic dystrophy 5; cranioectodermal dysplasia 4; and nephronophthisis 13. Orthologous to human WDR19 (WD repeat domain 19). [provided by Alliance of Genome Resources, Apr 2022]
