Figure 2: Pex19p forms soluble complexes with PMP22 in the cytosol. A) Overexpression of Pex19p stabilizes the coexpressed PMP22 in the cytosol. CHO-K1 cells expressing PMP22-HA alone (lanes 1–3) or together with FLAG-Pex19p (lanes 4–6) were resuspended with a buffer containing 100 μg/mL of digitonin to permeabilize the plasma membrane, and analyzed directly (T; lanes 1 and 4) or after separation into cytosolic (C; lanes 2 and 5) and organelle-containing (O; lanes 3 and 6) fractions. Equal aliquots of each fraction were analyzed by SDS–PAGE and immunoblotting with the indicated antibodies. Lactate <t>dehydrogenase</t> <t>(LDH)</t> and Pex14p are markers for cytosolic and organelle fractions, respectively. B) Pex19p binds to PMP22 in the cytosol. Cytosolic fraction from CHO-K1 cells overexpressing FLAG-Pex19p or PMP22-HA plus FLAG-Pex19p was subjected to immunoprecipitation (IP) with pre-immune serum (lanes 3 and 4) or anti-HA antibody (lanes 5 and 6). Input (10% of that used for IP; lanes 1 and 2) and immunoprecipitates were analyzed by SDS–PAGE and immunoblotting using the indicated antibodies. C) Farnesylation of Pex19p increases the binding affinity of Pex19p toward PMP22. Whole-cell lysates (WCLs) from CHO-K1 cells each expressing PMP22-HA together with epitope-tagged Pex19p variants, including Myc-Pex19p (WT, lanes 1 and 5), Myc-Pex19p-C296S (C296S, lanes 2 and 6), FLAG-Pex19p (WT, lanes 3 and 7) and FLAG-Pex19p-C296S (C296S, lanes 4 and 8) were subjected to IP with anti-FLAG agarose beads. Input (10% of that used for IP; lanes 1–4) and immunoprecipitates (lanes 5–8) were analyzed by SDS–PAGE and immunoblotting with anti-HA, anti-Pex19p and anti-α-tubulin antibodies. Solid and open arrowheads show unmodified and farnesylated epitope-tagged Pex19p, respectively. Tubulin was analyzed as a loading control.

Figure 2: Pex19p forms soluble complexes with PMP22 in the cytosol. A) Overexpression of Pex19p stabilizes the coexpressed PMP22 in the cytosol. CHO-K1 cells expressing PMP22-HA alone (lanes 1–3) or together with FLAG-Pex19p (lanes 4–6) were resuspended with a buffer containing 100 μg/mL of digitonin to permeabilize the plasma membrane, and analyzed directly (T; lanes 1 and 4) or after separation into cytosolic (C; lanes 2 and 5) and organelle-containing (O; lanes 3 and 6) fractions. Equal aliquots of each fraction were analyzed by SDS–PAGE and immunoblotting with the indicated antibodies. Lactate dehydrogenase (LDH) and Pex14p are markers for cytosolic and organelle fractions, respectively. B) Pex19p binds to PMP22 in the cytosol. Cytosolic fraction from CHO-K1 cells overexpressing FLAG-Pex19p or PMP22-HA plus FLAG-Pex19p was subjected to immunoprecipitation (IP) with pre-immune serum (lanes 3 and 4) or anti-HA antibody (lanes 5 and 6). Input (10% of that used for IP; lanes 1 and 2) and immunoprecipitates were analyzed by SDS–PAGE and immunoblotting using the indicated antibodies. C) Farnesylation of Pex19p increases the binding affinity of Pex19p toward PMP22. Whole-cell lysates (WCLs) from CHO-K1 cells each expressing PMP22-HA together with epitope-tagged Pex19p variants, including Myc-Pex19p (WT, lanes 1 and 5), Myc-Pex19p-C296S (C296S, lanes 2 and 6), FLAG-Pex19p (WT, lanes 3 and 7) and FLAG-Pex19p-C296S (C296S, lanes 4 and 8) were subjected to IP with anti-FLAG agarose beads. Input (10% of that used for IP; lanes 1–4) and immunoprecipitates (lanes 5–8) were analyzed by SDS–PAGE and immunoblotting with anti-HA, anti-Pex19p and anti-α-tubulin antibodies. Solid and open arrowheads show unmodified and farnesylated epitope-tagged Pex19p, respectively. Tubulin was analyzed as a loading control.
