Figure 4. PSD-95 decreased ASIC2a cell surface expression.

Figure 4

A–C, CHO cells were transfected with HA-ASIC2a and/or PSD-95, with DsRed added to keep total cDNA constant. A, Coimmunoprecipitation of ASIC2a with PSD-95. In the top panels, cell lysates were immunoprecipitated (IP) with anti-PSD-95 antibody, and then immunoblotted (IB) for ASIC2a (anti-HA). The bottom panels shows immunoblots of cell lysates. B, Immunoblot (anti-HA) of biotinylated (surface) and total ASIC2a. Lanes for surface and total protein in A and B were from the same gel and film exposure respectively, but were arranged for clarity. C, Quantification of relative ASIC2a surface expression with and without coexpressed PSD-95 (n = 9; *P<0.05).
