Abstract excerpt
The ability of a motif of the CYP17 5' untranslated region, created by a polymorphic T to C substitution, to bind to the human transcription factor Sp-1 was investigated. No binding of any of the polymorphic alleles was observed in electromobility shift assay. No other sequence within +1 to +100 of each of the CYP17 alleles formed complex with the Sp-1 or enhanced binding to the polymorphic CACC box. Genotyping...
