Kidney-derived aspartic protease-like protein (KAP), initially identified in the mouse kidney, is a novel aspartic protease exclusively expressed in the lung and spleen as well as the kidney. Its orthologues have been identified in the human and rat, and termed napsin. We performed in situ hybridization analysis to determine the cellular expression of napsin mRNA in the kidney, lung, and lymphatic organs of adult mice and to demonstrate, for the first time, its expression patterns in ontogeny. In the adult mouse kidney, extremely intense signals for napsin mRNA were observed in the proximal straight and convoluted tubules, in agreement with a previous study. The first signals for napsin mRNA during nephrogenesis occurred selectively in mesonephric tubules at embryonic day 13, and in metanephric tubules from embryonic day 14. In the lung, a distribution restricted to type II alveolar cells or their precursors was found from embryonic day 15, at the onset of type II cell differentiation, to the adult stage. In the spleen, the mRNA was expressed in lymph nodules of the white pulp and the marginal zone-namely, B-lymphocyte-rich regions from postnatal day 0 to adult. The lymph node and Peyer's patch displayed similar expression patterns, but T cell-dependent areas in these organs and the thymus lacked such signals. These findings suggest that mouse napsin possesses crucial functional roles not only in the kidney but also in the lung and lymphatic tissues, even during fetal stages.
