Variants of human glycoprotein hormone alpha chain: compositions and uses thereof
View Patent ↗The present invention provides human glycoprotein hormone (hGPH) α-chain splice variants, including isolated nucleic acids encoding these variants and the encoded amino acid sequences, as well as antibodies, antisense oligonucleotides, expression vectors and host cells comprising these sequences. The present invention further discloses the use of these sequences in the diagnosis, prevention and treatment of symptoms, diseases and disorders related to glycoprotein hormones.
1. An isolated polynucleotide comprising the nucleic acid sequence of SEQ ID NO: 1.
2. An isolated polynucleotide encoding a polypeptide having at least one hGPH activity wherein said polynucleotide comprises nucleotides 190-282 of SEQ ID NO: 1 in a polynucleotide of at least 695 bases.
3. The polynucleotide according to claim 1 encoding a polypeptide having at least one hGPH α-chain activity.
4. An isolated polynucleotide comprising a nucleic acid sequence encoding a polypeptide having the sequence set forth in SEQ ID NO: 2.
5. An isolated polynucleotide comprising a nucleic acid sequence complementary to the nucleic acid sequence according to claim 4 or claim 2 .
6. An expression vector comprising the polynucleotide sequence of claim 1 or claim 2 .
7. A host cell comprising the vector according to claim 6 .
8. A process for producing a polypeptide which comprises:
culturing the host cell according to claim 7 , wherein the host cell is a transformed carrot cell, under conditions suitable to produce the polypeptide encoded by the polynucleotide; and
recovering said polypeptide.
9. The process of claim 8 , wherein the transformed carrot cell is a cell from carrot callus.
10. The process of claim 8 , wherein the conditions comprise culturing the transformed carrot cell in suspension.
