Abstract

Lactoferrin (Lf) has been shown to have a role in the immune system and in early development of the mouse embryo. A specific receptor for Lf has been suggested to mediate the functions of Lf. We have recently identified a Lf receptor (LfR) in human fetal small intestine. We therefore hypothesized that the mouse homologue of this protein functions as a LfR. We expressed mouse Lf (MLf) and the mouse homologue (MLfR) in a baculovirus-insect cell system. The recombinant MLfR (rMLfR) was purified by immobilized recombinant MLf (rMLf) affinity chromatography, demonstrating an interaction between rMLf and the rMLfR. RT-PCR revealed that MLfR was expressed in various tissues and during embryonic development. Immunohistochemical analysis revealed that the MLfR was localized in various tissues including small intestinal epithelium, stomach, kidney, ovary, and various regions of brain. In summary, the MLfR functions as a receptor for MLf, is expressed and localized in various tissues, and may be involved in the indispensable function of MLf during early embryonic development.
