Predicted to be involved in cilium assembly; regulation of protein localization; and smoothened signaling pathway. Predicted to act upstream of or within several processes, including embryonic digit morphogenesis; in utero embryonic development; and neuroepithelial cell differentiation. Predicted to be located in membrane. Predicted to be part of MKS complex. Predicted to be active in ciliary membrane and ciliary transition zone. Human ortholog(s) of this gene implicated in Joubert syndrome 20 and Meckel syndrome. Orthologous to human TMEM231 (transmembrane protein 231). [provided by Alliance of Genome Resources, Apr 2022]
