MSY2 containing fractions (tubes 2-8) were combined and immunoprecipitated with excess affinity-purified antibody to MSY2. To maximize the yield of the MSY2�RNP complex, a second immunoprecipitation was performed and the precipitates were combined. Tubes 12-18 were combined for polysomes. (<I>A</I> and <I>B</I>) cDNA clones from an MSY2-bound subtracted cDNA library screened with MSY2-bound and polysomal cDNA probes, respectively. (<I>C</I> and <I>D</I>) The clones from the polysomal cDNA library screened with MSY2-bound and polysomal cDNA probes, respectively.</P>
