OR, RTP1S, and RTP2 interact with each other in HEK293T cells.

<p><i>Left</i>, interactions among MOR258-5 (Category 1), RTP1S and RTP2. <i>Right</i>, interactions among MOR23-1 (Category 2), RTP1S and RTP2. <i>First and second panels</i>, protein lysates of HEK293T cells transfected with Flag-tagged OR and/or HA-tagged RTP1S and Flag-tagged/HA-tagged RTP2 and blotted with anti-Flag or anti-HA antibody. <i>Third panels</i>, co-immunoprecipitation of Flag-tagged proteins with anti-HA antibody. <i>Fourth panels</i>, co-immunoprecipitation of HA-tagged proteins with anti-Flag antibody.
