Abstract: The disclosure features fusion proteins that are conditionally active variants of IL-2. In one aspect, the full-length polypeptides of the invention have reduced or minimal cytokine-receptor activating activity even though they contain a functional cytokine polypeptide. Upon activation, e.g., by cleavage of a linker that joins a blocking moiety, e.g., a steric blocking polypeptide, in sequence to the active cytokine, the cytokine can bind its receptor and effect signaling.

Abstract: Disclosed herein are inducible monovalent target-binding proteins which are activated upon protease cleavage. Pharmaceutical compositions comprising the binding proteins disclosed herein and methods of using such formulations are further provided.

Abstract: The present invention relates to compositions comprising polypeptides, especially polypeptides capable of specifically binding predetermined antigens. The polypeptide in the composition comprises at least two antigen binding sites. These at least two antigen binding sites are located on a single polypeptide chain. One of the at least two antigen binding sites specifically binds the human CD3 antigen. The polypeptide may exist in both monomeric form and multimeric form. The multimeric form of the polypeptide constitutes no more than 5% of the total weight of the combined monomeric and multimeric forms of said polypeptide.
