A [auth B] | PF09294 | Interferon-alpha/beta receptor, fibronectin type III (Interfer-bind) | Interferon-alpha/beta receptor, fibronectin type III | Members of this family adopt a secondary structure consisting of seven beta-strands arranged in an immunoglobulin-like beta-sandwich, in a Greek-key topology. They are required for binding to interferon-alpha [1]. | Domain |
