Predicted to enable lipoprotein particle receptor activity and low-density lipoprotein particle binding activity. Involved in several processes, including establishment of blood-brain barrier; establishment of skin barrier; and tricellular tight junction assembly. Acts upstream of or within protein localization to tricellular tight junction. Located in plasma membrane and tricellular tight junction. Is expressed in several structures, including alimentary system; genitourinary system; limb; liver; and respiratory system. Orthologous to human LSR (lipolysis stimulated lipoprotein receptor).
