Using G-free reporter constructs carrying multiple copies of wild-type or mutant GCMa-binding site (GBS) in front of a synthetic TATA box, we observed specific transcriptional activities of recombinant hGCMa/1 proteins prepared from a baculovirus--insect cell or Escherichia coli expression system. We further characterized GCMa/1-mediated transcriptional activation on the native syncytin promoter. Using G-free reporter constructs containing the native syncytin promoter, a TATA box downstream of the proximal GBS in the syncytin promoter was shown to be essential for the transcription activation directed by hGCMa/1.
