Web25 jan. 2024 · The HIF pathway acts as a central regulator of erythropoiesis by coordinating a series of cell-specific responses to hypoxia: (i) EPO production, (ii) indirect suppression of hepcidin by promotion of erythropoiesis, (iii) augmentation of enteric iron absorption and its plasma transport, and (iv) redistribution of endogenous iron stores. Web2 nov. 2010 · TEXT Description A2M is a 718-kD homotetrameric glycoprotein of plasma and extracellular spaces that was first recognized as a broad spectrum protease inhibitor. A2M is activated by proteases with which it interacts, and this proteolytic activation causes a conformational change that traps the protease within the A2M homotetramer.
