Function
NEPH1 is a member of the NEPH protein family, which includes NEPH2 (
KIRREL3,
MIMbr>
607761 and NEPH3 (
KIRREL2,
MIMbr>
607762. The cytoplasmic domains of these proteins interact with the C terminus of
podocin (NPHS2; MIM 604766). NEPH1 is expressed in
filtration slits of kidney
podocytes
Podocytes are cells in Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocytes make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place. Bowman's capsule ...

Ultrafiltration (UF) is a variety of membrane filtration in which forces such as pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in t ...
