Abstract: Described herein are compounds that can bind CaSR and/or a CaSR extracellular domain and formulations thereof. Also described herein are methods of inhibiting CaSR and/or treating a disease or disorder associated with a mutation in CaSR by administering a compound or formulation thereof described herein. Also described herein are assays that can be used to identify compounds that can bind an extracellular domain of CaSR.

Abstract: A method for constructing an metal ion binding motif by identifying an metal ion binding peptide that binds an metal ion with specificity, ascertaining at least a portion of a nucleic acid sequence encoding the metal ion binding peptide, tailoring the nucleic acid sequence encoding the metal ion binding peptide into an metal ion binding site, identifying a host protein and a relevant portion of the nucleic acid sequence of the host protein, operatively linking the tailored nucleic acid sequence encoding the metal ion binding peptide and the host protein nucleic acid sequence into an metal ion binding motif sequence, and expressing metal ion binding motif sequence, in which the nucleic acid sequence encoding the metal ion binding peptide is tailored so as to achieve the metal ion binding motif with a desired specificity for the metal ion. Also, the proteins encoded by the metal ion binding motif sequence as constructed by the method.

Abstract: Compositions and methods for reconstituting a protein of interest in the plasma membrane of a Xenopus oocyte are disclosed. The method generally includes combining a preassembled membrane protein or proteins with a liposome to prepare a proteo-liposome. The proteo-liposome can have a specific composition of lipids. The proteo-liposome is incubated for sufficient time and under conditions suitable for the protein of interest to fold, associate with, or insert into the liposome's lipid bilayer. In some embodiments, the protein or proteins assemble into a protein channel or complex on or in the proteo-liposome's membrane. The treated oocytes can be used to determine the structure, function, or activity of the membrane protein of interest, the effect of a lipid microenvironment on a membrane protein of interest, or to identify compounds that modulate the function or activity of the membrane protein of interest.

Abstract: Provided is a protein contrast agent for enhancing an MRI image and comprising a polypeptide having a conformation presenting at least five oxygen atoms positioned to chelate at least one paramagnetic metal ion such as Gd3+, each oxygen atom being between about 2 angstrom units and about 5 angstrom units from the metal ion; the metal ion has at least one water molecule electrostatically interacting a distance of less than about 10 angstrom units a target-specific moiety conjugated thereto, at least one polyethylene glycol molecule, and a paramagnetic metal ion. Also provided is a method of obtaining an enhanced MRI image using the protein contrast agent to a T2/T1 or T1/T2 intensity ratio of the MRI image; and (d) obtaining an image of the T2/T1 or T1/T2 intensity ratio.

Abstract: Analyte sensors, methods for producing and using analyte sensors, methods of detecting and/or measuring analyte activity, detecting pH change, and/or, controlling the concentration of an analyte in a system, are disclosed. Embodiments of the analyte sensors according to the disclosure can provide an accurate and convenient method for characterizing analyte activity, detecting pH change, controlling the concentration of an analyte in a system, and the like, in both in vivo and in vitro environments, in particular in living cell imaging.
