Presence of multiple species of polypeptides immunologically related to transcription factor TFIIIA in adult Xenopus tissues.

abstract：:Human transcription factor Sp1 contains three contiguous repeats of the C2H2-type zinc finger motif and binds to the decanucleotide sequence 5'-(G/T)GGGCGG(G/A)(G/A)(C/T)-3' (GC box). In order to determine whether the three-zinc finger peptide Sp1(530-623) has selectivity for sequence outside the GC box, we used a sel...
