This disclosure relates to hybrid antigen binding molecules including at least two polypeptide chains, with at least one polypeptide chain comprises an antigen binding moiety linked to an amino acid sequence of a subunit of a heterodimeric proteinaceous hormone. Also disclosed are methods of making and using such hybrid antigen binding molecules for diagnosis and/or therapy.

Compositions and methods of producing hybrid antigen binding molecules and uses thereof

A novel FSH mutant with increased glycosylation and longer half-lifes for use in inducing folliculogenesis in human patients is described. The FSH mutant permits the use of lower cumulative doses of FSH to achieve the same or better clinical result.

FSH beta mutants that are glycosilated at residues N55 and T57

The inventors have designed novel FSH mutants with increased glycosylation and longer half-lives for use in inducing folliculogenesis in human patients. The use of a FSH mutant preparation of the invention permits the use of lower cumulative doses of FSH to achieve the same or better clinical result.

Mutant glycoproteins

A hybrid protein includes two coexpressed amino acid sequences forming a dimer. Each sequence contains the binding portion of a receptor, such as TBP1 or TBP2, or a ligand, such as IL-6, IFN-&#x3b2; and TPO, linked to &#x3b1; subunit of a natural heterodimeric scaffold. Each coexpressed sequence contains a corresponding subunit so as to form a heterodimer upon expression. Corresponding DNA molecules, expression vectors and host cells are also disclosed as are pharmaceutical compositions and a method of producing such proteins.

Homogeneity and secretion of a recombinant follicle stimulating hormone (FSH) in mammalian systems

A hybrid protein includes two coexpressed amino acid sequences forming a dimer. Each sequence contains the binding portion of a receptor, such as TBP1 or TBP2, or a ligand, such as IL-6, IFN-&bgr; and TPO, linked to a subunit of a heterodimeric proteinaceous hormone, such as hCG. Each coexpressed sequence contains a corresponding hormone subunit so as to form a heterodimer upon expression. Corresponding DNA molecules, expression vectors and host cells are also disclosed as are pharmaceutical compositions and a method of producing such proteins.

Hybrid heterodimeric protein hormone comprising a TNF binding protein and a glycoprotein hormone subunit and method of using same

A hybrid protein includes two coexpressed amino acid sequences forming a dimer. Each sequence contains the binding portion of a receptor, such as TBP1 or TBP2, or a ligand, such as IL-6, IFN-&bgr;and TPO, linked to a subunit of a heterodimeric proteinaceous hormone, such as hCG. Each coexpressed sequence contains a corresponding hormone subunit so as to form a heterodimer upon expression. Corresponding DNA molecules, expression vectors and host cells are also disclosed as are pharmaceutical compositions and a method of producing such proteins.

Hybrid heterodimeric protein hormone

The present invention pertains to an alpha, beta-heterodimeric polypeptide having binding affinity to vertebrate luteinizing hormone (LH) receptors and vertebrate follicle stimulating hormone (FSH) receptors comprising a glycoprotein hormone alpha-subunit polypeptide and a non-naturally occurring beta-subunit polypeptide, wherein the beta-subunit polypeptide is a chain of amino acids comprising the following four joined subsequences: (a) a first subsequence homologous to the amino acid sequence of residues 1-93 of the beta-subunit selected from the group consisting of human chorionic gonadotrophin (hCG), vertebrate luteinizing hormone (LH), vertebrate follicle stimulating hormone (FSH), and vertebrate thyroid stimulating hormone (TSH); (b) a second subsequence homo logous to the amino acid sequence of residues 94-97 of the beta-subunit selected from the group consisting of human chorionic gonadotrophin (hCG) and vertebrate luteinizing hormone (LH); (c) a third subsequence homologous to the amino acid sequence of residues 98-100 of the beta-subunit selected from the group consisting of human chorionic gonadotrophin (hCG), vertebrate luteinizing hormone (LH), vertebrate follicle stimulating hormone (FSH), and vertebrate thyroid stimulating hormone (TSH); and (d) a fourth subsequence homologous to the amino acid sequence of residues 101-110 of the beta-subunit of vertebrate follicle stimulating hormone.
