Predicted to enable hedgehog receptor activity. Predicted to be involved in cilium assembly 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 ciliary transition zone; membrane; and microtubule organizing center. Predicted to be part of MKS complex. Human ortholog(s) of this gene implicated in Joubert syndrome 27 and Meckel syndrome. Orthologous to human B9D1 (B9 domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
