摘要：
Disclosed herein are immunoglobulin fusion proteins that have a first antibody region attached to an extender fusion region. The extender fusion region contains a therapeutic agent and a beta strand secondary structure. The extender fusion region may contain 7 or fewer consecutive amino acids based on or derived from an ultralong CDR3. Alternatively, the extender fusion region contains a rigid stalk protein structure, but does not contain an amino acid sequence based on or derived from an ultralong CDR3. The extender fusion region may also have one or more linkers or proteolytic cleavage sites. The immunoglobulin fusion proteins may have additional therapeutic agents and extender fusion regions. Also disclosed herein are pharmaceutical compositions of immunoglobulin fusion proteins and methods for using the immunoglobulin fusion proteins for the treatment or prevention of a disease or condition in a subject.
