Loss of glomerular foot processes is associated with uncoupling of podocalyxin from the actin cytoskeleton

Abstract excerpt

Podocalyxin (PC), the major sialoprotein of glomerular epithelial cells (GECs), helps maintain the characteristic architecture of the foot processes and the patency of the filtration slits. PC associates with actin via ezrin, a member of the ERM family of cytoskeletal linker proteins. Here we show that PC is linked to ezrin and the actin cytoskeleton via Na(+)/H(+)-exchanger regulatory factor 2 (NHERF2), a...
