RESUMO
We have examined the transcription in a cell-free system of all the members of a highly regulated gene family, the beta-like hemoglobin genes of the goat. These five genes, which code for embryonic, fetal, juvenile, and adult beta-globin proteins, are all transcribed to roughly the same extent in the in vitro system. In all cases initiation of transcription is accurate. However, two goat beta-globin pseudogenes, as well as several artificially constructed deletion mutants, are not transcribed in vitro. A common feature of the transcriptionally inactive genes is the lack of an AT-rich consensus sequence just upstream of the presumptive initiation site.
