Purified cpSRP interacts with purified LHCP. (A) Silver-stained gel of recombinant cpSRP protein; 8% polyacrylamide gel, 0.3 μg of protein. Coomassie gel of recombinant pLHCP protein; 12% polyacrylamide gel, 2 μg of protein. (B) Coprecipitation of pLHCP with anti-cpSRP54 antibodies (lanes 1 and 2) or glutathione Sepharose beads (GS; lanes 3 and 4), which bind GST-43, occurs in the presence of cpSRP. Coprecipitation of cpSRP54 and cpSRP43 with anti-LHCP occurs in the presence of pLHCP (lanes 5–8).
