title: Structure and expression of human alpha-interferon genes.
abstract: cDNA was prepared from induced leukocyte poly(A) RNA and cloned in Escherichia coli. Interferon (IFN)-alpha cDNA clones were isolated by subculture cloning using a translation hybridization assay. Definitive identification of the clones was based on the production of an interferon-like protein by the transformed bacteria. Different IFN-alpha cDNAs, with characteristic target cell specificities, were identified. The cloned cDNAs typically encode a mature polypeptide of 166 (or, in the case of IFN-alpha 2, 165) amino acids and a signal sequence of 23 amino acids.
