The localization of the brain-specific inorganic phosphate transporter suggests a specific presynaptic role in glutamatergic transmission.


Molecular cloning has recently identified a vertebrate brain-specific Na+-dependent inorganic phosphate transporter (BNPI). BNPI has strong sequence similarity to EAT-4, a Caenorhabditis elegans protein implicated in glutamatergic transmission. To characterize the physiological role of BNPI, we have generated an antibody to the protein. Immunocytochemistry… (More)
