Predicted to enable protein dimerization activity. Involved in epithelial cell morphogenesis; protein transport from ciliary membrane to plasma membrane; and regulation of neuron death. Located in centrosome and cilium. Is expressed in several structures, including brain; genitourinary system; gut; lens; and vertebral axis musculature. Orthologous to human RILPL1 (Rab interacting lysosomal protein like 1). [provided by Alliance of Genome Resources, Apr 2022]
