title: DNA sequence of a major human leukocyte interferon gene.
abstract: The gene for human leukocyte interferon alpha 2 (designated either LeIF A or HuIFN-alpha 2) has been isolated from a human genome library. The DNA sequence of this gene demonstrates that it lacks introns. The 3' noncoding sequences of the IFN-alpha 2 gene correspond to two types of IFN-alpha 2 cDNA clones we have isolated that have alternate sites of polyadenylylation. A comparison of seven human IFN-alpha sequences shows that they are homologous in the 5' flanking region and contain identical "TATA box" sequences. The recombinant lambda clone containing the IFN-alpha 2 gene also contains two copies of the "Alu family" repeat sequence.
