Predicted to enable phospholipid binding activity. Involved in cilium assembly; limb morphogenesis; and positive regulation of smoothened signaling pathway. Located in ciliary basal body and ciliary transition zone. Is expressed in apical ectodermal ridge; limb bud; and limb mesenchyme. Used to study polydactyly. Orthologous to human CIBAR1 (CBY1 interacting BAR domain containing 1). [provided by Alliance of Genome Resources, Apr 2022]
