The present invention relates to novel osteoprotegerin variant proteins (GYPs) that demonstrate reduced binding affinity for their ligand TRAIL when compared to wild-type osteoprotegerin. Nucleic acids which encode these GYPs are also provided. Recombinant vectors and host cells expressing these GYPs are also encompassed as are methods of producing recombinant GYPs. The present invention also relates to compositions comprising these GYPs, and to methods of treating bone diseases characterised by increased bone turnover and/or loss. The GYPs of the invention are useful for preventing bone resorption and may be used to treat any condition resulting in abnormal bone turnover or bone loss such as osteoporosis, hypercalcemia, Paget's disease of bone, multiple myeloma, bone cancer and bone loss due to rheumatoid arthritis or osteomyelitis, and the like.

Osteoprotegerin variant proteins

The present invention relates to novel osteoprotegerin variant proteins (OVPs) that demonstrate reduced binding affinity for their ligand TRAIL when compared to wild-type osteoprotegerin. Nucleic acids which encode these OVPs are also provided. Recombinant vectors and host cells expressing these OVPs are also encompassed as are methods of producing recombinant OVPs. The present invention also relates to compositions comprising these OVPs, and to methods of treating bone diseases characterised by increased bone turnover and/or loss. The OVPs of the invention are useful for preventing bone resorption and may be used to treat any condition resulting in abnormal bone turnover or bone loss such as osteoporosis, hypercalcemia, Paget's disease of bone, multiple myeloma, bone cancer and bone loss due to rheumatoid arthritis or osteomyelitis, and the like.

The invention relates to a chimeric antibody conjugate comprising an antigen binding region of a non-human antibody and an immunoglobulin constant region which comprises at least one Cdomain or epitope thereof, with the proviso that the constant region is not a naturally occurring Ffragment. A bifunctional molecule for use in labelling an antibody derived from a first species, the bifunctional molecule comprising a binding region which binds to the antibody of the first species or to one or more groups provided thereon, and a constant region derived from an antibody of a second species, the constant region comprising at least one Cdomain or an epitope thereof. The present invention relates to bifunctional molecules and complexes which are useful as positive control reagents in antibody based diagnostic tests. The present invention also relates to polynucleotides encoding these bifunctional molecules, and to diagnostic assays involving the use of these molecules.

Bifunctional molecules

The present invention provides a method for the mutation, synthesis and selection of a protein which binds to a target molecule, the method comprising: (a) incubating a replicable mRNA molecule encoding the protein with ribonucleoside triphosphate precursors of RNA and an RNA-directed RNA polymerase, wherein the RNA-directed RNA polymerase replicates the mRNA molecule but introduces mutations thereby generating a population of mutant mRNA molecules; (b) incubating the mutant mRNA molecules from step (a) with a translation system under conditions which results in the synthesis of population of mutant proteins such that after translation, mutant proteins are linked to their encoding mRNA molecules thereby forming a population of mutant proteins such that after translation, mutant proteins are linked to their encoding mRNA molecules thereby forming a population of mutant/mRNA complexes; (c) selecting one or more mutant protein/mRNA complex(es) by exposing the population of mutant protein/mRNA complexes from step (b) to the target molecule and recovering the mutant protein/mRNA complex(es) bound thereto.
