Aspects of the invention provide methods for harnessing the potential of proteins that occur naturally (e.g., in humans) and that have serious but finite toxicity. Aspects of the invention relate to a quantitative systems-biological and structural approach to design a class Mof chimeric proteins that avoid the toxicity of protein drugs while retaining their desired activities. In particular, chimeric proteins containing a variant form of a natural protein fused to a targeting moiety may be administered to a subject to target a signal (e.g., induction of apoptosis) to particular cells without having a generalized toxic effect.

Disclosed herein are immunoglobulin fusion proteins comprising a first antibody region, a first therapeutic agent, and a first connecting peptide; wherein the first therapeutic agent is attached to the first antibody region by the connecting peptide; and wherein the connecting peptide does not comprise a region having beta strand secondary structure. The connecting peptide may comprise an extender peptide. The extender peptide may have an alpha helical secondary structure. The connecting peptide may comprise a linker peptide. The linker peptide may not comprise any secondary structure. Also disclosed herein are compositions comprising the immunoglobulin fusion proteins and methods for using the immunoglobulin fusion proteins for the treatment or prevention of a disease or condition in a subject.

The present invention relates to a method for prolonging half-life of a protein or a (poly)peptide by replacing one or more amino acid residues of the protein. Further, the present invention is about the protein having a prolonged half-life prepared by the method above.

This invention is directed to compositions and methods for the treatment and prevention of hypoglycemic complications. Specifically, aspects of the invention are drawn to the use of leptin for the treatment and prevention of hypoglycemic complications.

[Problem] Provided is a calmodulin-like skin protein (CLSP) derivative, which has an activity to suppress neuronal cell dysfunction or cell death associated with e.g., Alzheitner's disease stronger than of humanin, and which is insensitive to an inhibitory action by an inhibitor of the activity; a polypeptide which has an action/activity to potentiate or protect the Alzheimer's disease-suppressing activity by CLSP; and the like.

[Solution] A derivative (mutant) of calmodulin-like skin protein (CLSP), characterized by including an endogenous humanin-homogenous region (EHR), which is the core of the activity to suppress the neuronal cell dysfunction or neuronal cell death associated with Alzheimer's disease (CLSP activity), and not including a region to which an inhibitor of the CLSP activity binds; a pharmaceutical composition to suppress the neuronal cell dysfunction or neuronal cell death associated with Alzheimer's disease, the composition including the mutant as an active ingredient; and the like.
