Podocalyxin Like Protein 2 (PODXL2)

PODXL2, PLEXIN-D1, GATA-2, and TMCC1 are located within the smaller critical interval of the Pakistani HCFP family. Podocalyxin, a sialoglycoprotein, is thought to be the major constituent of the glycocalyx of podocytes. 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.Podocytes are highly differentiated epithelial cells with interdigitating foot processes covering the outer aspect of the glomerular basement membrane. Other biological activities of the encoded protein include: binding in a membrane protein complex with Na+/H+ exchanger regulatory factor to intracellular cytoskeletal elements, playing a role in hematopoetic cell differentiation, and being expressed in vascular endothelium cells and binding to L-selectin.
