Podocalyxin, a sialoglycoprotein, is thought to be the major constituent of the glycocalyx of podocytes[1]. It coats the secondary foot processes of the podocytes. It is negatively charged and thus functions to keep adjacent foot processes separated, thereby keeping the urinary filtration barrier open.[2]
