Hydrophobie cluster analysis reveals duplication in the external structure of human α‐interferon receptor and homology with γ‐interferon receptor external domain

摘要

>Evidence is presented, based on sequence comparison according to Hydrophobic Cluster Analysis, of a structural and evolutionary relationship between the human α/β-interferon receptor and the human and mouse γ-interferon receptor. These results predict that the human α/β-interferon receptor extracellular part is organised in two homologous subdomains connected by a proline linker. They also predict that both subdomains present some homologies to the external domain of mouse and human γ interferon receptor.
