Summary of the all of the clones from the two immunoprecipitations that demonstrated EF-67 specific binding. Clones are organized according to the presence or absence or the listed 3′ UTR cis-elements. All of the pentamer containing clones also contain poly(U) tracts, which are defined as a least two tracts with a minimum of five uridines or at least four tracts with a minimum of four uridines.
