FIGURE 3:
Pdi1 physically interacts with ApoB29 and CPY*. Native immunoprecipitation reactions were performed using anti-HA resin or unconjugated Sepharose (Mock), using lysates from wild-type yeast strains expressing ApoB29 (A) or CPY* (B). In both cases, cell lysates were also examined that contained a vector control (–) in place of the ApoB29 or CPY* (+) expression vector. A total of 1% of the input for the precipitation was also examined (Lysate). After precipitation and SDS–PAGE, the indicated proteins were examined by immunoblot analysis.
