Predicted to enable chemokine binding activity; protein-folding chaperone binding activity; and signaling receptor binding activity. Involved in several processes, including lung development; positive regulation of platelet activation; and response to hyperoxia. Acts upstream of or within cell adhesion; positive regulation of cell migration; and tube morphogenesis. Located in apical plasma membrane. Biomarker of adult respiratory distress syndrome; bacterial pneumonia; nephrosis; and oligohydramnios. Orthologous to human PDPN (podoplanin); INTERACTS WITH 2,3,7,8-tetrachlorodibenzodioxine; 3'-amino-3'-deoxy-N(6),N(6)-dimethyladenosine; 3H-1,2-dithiole-3-thione.
