Summary: Predicted to enable cholesterol binding activity. Involved in several processes, including cholesterol homeostasis; positive regulation of growth rate; and regulation of egg-laying behavior. Predicted to be located in late endosome and lysosome. Predicted to be active in plasma membrane. Is expressed in several structures, including head neurons; hermaphrodite gonad; hypodermis; lumbar neurons; and pharynx. Used to study Niemann-Pick disease. Human ortholog(s) of this gene implicated in Niemann-Pick disease type C1. Orthologous to several human genes including NPC1 (NPC intracellular cholesterol transporter 1).
