Uromodulin: ProductsUromodulin (also Tamm-Horsfall glycoprotein or THP) is an 85 - 95 kDa urinary glycoprotein. It is secreted by renal tubule epithelium, acts as a binding protein for IL-1, TNF-α and C1q, activates resting monocytes and promotes neutrophil phagocytosis. Uromodulin forms high molecular weight oligomers that line the kidney tubules. Human Uromodulin is GPI-linked. Human Uromodulin is 78% aa identical to mouse Uromodulin.
