Abstract:
A genomic sequence approximately 5 kb in length designated the alpha-1-antitrypsin-related gene (ATR), showing considerable homology to the human alpha-1-antitrypsin (AAT) gene, was identified 10 kb downstream of the authentic AAT gene. The AAT and ATR genes were introduced separately into L-cells by transfection in order to establish a method for distinguishing between expression of the two genes. RNA probes from the cloned ATR region were then used in a ribonuclease protection assay against RNA from a range of human adult and fetal tissues. No evidence of expression of ATR was found, indicating that this region is probably a pseudogene.
