Nephrin is a protein necessary for the proper functioning of the renal filtration barrier. The renal filtration barrier consists of fenestrated endothelial cells, the glomerular basement membrane, and the podocytes of epithelial cells. Nephrin is a transmembrane protein that is a structural component of the slit diaphragm.^[1]

A defect in the gene for nephrin is associated with congenital nephrotic syndrome of the Finnish type and causes massive amounts of protein to be leaked into the urine, or proteinuria. Nephrin is also required for cardiovascular development.^[2]

Interactions

Nephrin has been shown to interact with FYN,^[3][4] NPHS2,^[5] CD2AP,^[6] KIRREL,^[7][8] CTNND1,^[6] CDH3^[6] and CASK.^[6]
