Podoplanin

Patent Pending Podoplanin is a protein that in humans is encoded by the PDPN gene. This gene encodes a type-I, integral membrane, heavily O-glycosylated glycoprotein with diverse distribution in human tissues. The physiological function of this protein may be related to its mucin-type character. The homologous protein in other species has been described as a differentiation antigen and influenza-virus receptor. The specific function of this protein has not been determined but it has been proposed as a marker of lung injury. Alternatively spliced transcript variants encoding different isoforms have been identified.
