Inorganic Phosphate Modulates the Expression of the NaPi-2a Transporter in the trans-Golgi Network and the Interaction with PIST in the Proximal Tubule

Coimmunoprecipitation assays. (a) Coimmunoprecipitation of PIST and NaPi2a using rat kidney homogenates from rats fed a control diet, and with an anti-PIST antibody. (b) Coimmunoprecipitation in rats acutely adapted for 4 hours from low to high (L-H) and from high to low (H-L) Pi diet, using non-BBM homogenates. SN: supernatant (nonprecipitated samples); IP: immunoprecipitated; WB: Western blotting.
