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

Figure 6

Overexpression of GFP-PIST in OK cells maintains NaPi4 in the trans-Golgi, independently of the concentration of Pi in the cell culture medium (0.1 mM versus 2 mM Pi).
