FIGURE 10:
CCT7 coimmunoprecipitates with other GPCRs. (A) Lysates of HEK 293 cells transiently expressing HA-MOR (HA-tagged rat μ-opioid receptor) alone or with CCT7-MYC were immunoprecipitated with an HA-specific monoclonal antibody and analyzed by immunoblotting with MYC- and HA-specific HRP-conjugated antibodies. Lysates of HEK 293 cells transiently expressing FLAG-DOR (FLAG-tagged rat δ-opioid receptor; B) or FLAG-DP (FLAG-tagged prostaglandin D2 receptor; C) alone or with CCT7-MYC were immunoprecipitated with a FLAG-specific monoclonal antibody and analyzed by immunoblotting with FLAG-specific polyclonal and HA-specific HRP-conjugated antibodies. The blots shown are representative of three separate experiments. IB, immunoblotting; IP, immunoprecipitation.
