... (1994)Identification of a GC element in the promotor of the murine L32 ribosomal protein L32 gene and the 3¢-ter-minal region of the human apolipoprotein A-I gene, capable of binding with murine and human ... GCC-elements of the rpL32 promoter and the 5¢-UTR of the human FMR1 gene. We further identify p56 as the Kru¨ppel-like transcription factor ZF5. We show, for the firsttime, that recombinant ... to the protein of interest. In the case of the rpL32 fragmentor the (GCC)9sequence, there are several repeatedZF5-binding sites within a single oligonucleotide.Therefore, the affinity of...
