we conclude that 1 ) proliferin secreted by cultured cell binds to cation-independent mannose 6-phosphate receptors and therefore may be a lysosomal protein or targeted to lysosomes , and 2 ) the concentration or activity of mannose 6-phosphate receptors in murine fetal and maternal liver and in placenta is regulated during pregnancy .
