Modified ubiquitin protein having specific binding activity to extra domain B of fibronectin

摘要

The present invention refers to novel hetero-multimeric proteins obtained from modified ubiquitin capable of binding the extradomain B of fibronectin (ED-B) with high affinity. Furthermore, the invention refers to fusion proteins comprising said recombinant protein fused to a pharmaceutically and/or diagnostically active component. The invention is further directed to the use of said proteins in medical treatment methods.
