Claims
- 1. An isolated DNA molecule which encodes Xenopus laevis bone morphogenetic protein selected from the group consisting of BMP-2A having amino acid sequence numbers 282 to 398 of SEQ ID No: 19, BMP-2B having amino acid sequence numbers 288 to 401 of SEQ ID NO: 20, and Vgr-1 having amino acid sequence numbers 328 to 426 of SEQ ID NO: 21.
- 2. The DNA molecule of claim 1, which has a nucleic acid sequence selected from the group consisting of nucleic acid sequence numbers 1093 to 1443 of SEQ ID NO: 6, nucleic acid sequence numbers 966 to 1307 of SEQ ID NO: 7, and nucleic acid sequence numbers 1068 to 1364 of SEQ ID NO: 8.
- 3. A host cell transformed with the isolated DNA molecule of claim 2.
- 4. A host cell transformed with a DNA molecule which encodes Xenopus laevis bone morphogenetic protein selected from the group consisting of BMP-2A having amino acid sequence numbers 282 to 398 of SEQ ID NO: 19, BMP-2B having amino acid sequence numbers 288 to 401 of SEQ ID NO: 20, and Vgr-1 having amino acid sequence numbers 328 to 426 of SEQ ID NO: 21.
- 5. The transformed host cell of claim 4, which is Escherichia coli HB101/pXbr22 (FERM BP-3066).
- 6. The transformed host cell of claim 4 which is Escherichia coli HB101/pXbr23 (FERM BP-3065).
- 7. The transformed host cell of claim 4, which is Escherichia coli HB101/pXbr41 (FERM BP-3065).
- 8. A method of using the transformed host cell of claim 4 comprising
- (a) culturing the transformed host cell under conditions to permit the expression of the bone morphogenetic protein,
- (b) maintaining the transformed host cell under the conditions of step (a) to accumulate the bone morphogenetic protein; and
- (c) collecting the protein obtained from the transformed host cell.
- 9. A method for preparing Xenopus laevis bone morphogenetic protein selected from the group consisting of BMP-2A having amino acid sequence numbers 282 to 398 of SEQ ID NO: 19, BMP-2B having amino acid sequence numbers 288 to 401 of SEQ ID NO: 20, and Vgr-1 having amino acid sequence numbers 328 to 426 of SEQ ID NO: 21, which comprises culturing a host cell transformed with the DNA molecule of claim 1, under conditions to permit the expression of the bone morphogenetic protein and recording said protein.
