Abstract
We have produced a cell line which lacks the protein tyrosine kinase JAK1 and is completely defective in interferon response. Complementation of this mutant with JAK1 restored the response, establishing the requirement for JAK1 in both the interferon-α/beta; and -γ signal transduction pathways. The reciprocal interdependence between JAK1 and Tyk2 activities in the interferon-α pathway, and between JAK1 and JAK2 in the interferon-γ pathway, may reflect a requirement for these kinases in the correct assembly of interferon receptor complexes.
