Predicted to enable lipid binding activity. Predicted to be involved in cilium assembly; lipoprotein transport; and nervous system development. Predicted to act upstream of or within cell projection organization and protein transport. Predicted to be located in ciliary transition zone. Predicted to be active in cilium. Is expressed in several structures, including central nervous system; genitourinary system; gut; respiratory system; and sensory organ. Orthologous to human UNC119B (unc-119 lipid binding chaperone B). [provided by Alliance of Genome Resources, Apr 2022]
