Cover Story: Legumain is a lysosomal cysteine protease and implicated in diverse physiological and pathophysiological processes; however, the upstream mechanisms regulating the expression and function of legumain are not well understood. Our study reveals that vitamin D3 (VD3) is a positive regulator of legumain expression and function, both in vitro and in vivo. On the other hand, we provide in vitro and in vivo evidence for the cleavage of vitamin D binding protein by legumain, suggesting a possible role for legumain in the regulation of VD3 metabolism. Finally, we show that legumain deficiency in vivo resulted in increased plasma levels of 25(OH)D3 and total VD3, as well as the altered expression of key renal enzymes involved in VD3 metabolism (CYP24A1 and CYP27B1). These findings suggest a reciprocal regulatory interplay between VD3 and legumain. View this paper
