Patent ID: 7192712

Claim:
A polynucleotide comprising a nucleotide sequence of a common marmoset-derived beta-actin gene or a partial nucleotide sequence thereof, wherein said nucleotide sequence is selected from the group consisting of: (1) the nucleotide sequence of SEQ ID NO: 1; (2) the nucleotide sequence of SEQ ID NO: 2; (3) a nucleotide sequence of a DNA which has any of nucleotide sequences as defined in (1) to (2), and is complementary to a mature mRNA containing a region from a 5′ cap to a poly(A) sequence; (4) a nucleotide sequence which is complementary to any of the nucleotide sequences as defined in (1) to (3); (5) a nucleotide sequence represented by nucleotide numbers 1126 to 1725 of the nucleotide sequence of SEQ ID NO: 2; (6) a nucleotide sequence comprising 20 to 60 consecutive nucleotides which is selected from the group consisting of: a nucleotide sequence having a length of 60 consecutive nucleotides, which begins at any nucleotide between nucleotide numbers 1360 to 1386, or 1435 to 1447 of the nucleotide sequence of SEQ ID NO: 2, and terminates at any nucleotide between nucleotide numbers 1419 to 1445, or 1494 to 1506 of the nucleotide sequence of SEQ ID NO: 2, respectively; a nucleotide sequence having a length of 50 consecutive nucleotides, which begins at any nucleotide between nucleotide numbers 1362 to 1393, or 1435 to 1447 of the nucleotide sequence of SEQ ID NO: 2, and terminates at any nucleotide between nucleotide numbers 1411 to 1442, or 1484 to 1496 of the polynucleotide sequence of SEQ ID No: 2, respectively; a nucleotide sequence having a length of 35 consecutive nucleotides, which begins at any nucleotide between nucleotide number 1366, 1371 to 1393, or 1435 to 1447 of the nucleotide sequence of SEQ ID No: 2, and terminates at any nucleotide between nucleotide numbers 1400, 1405 to 1427, or 1469 to 1481 of the nucleotide sequence of SEQ ID NO: 2, respectively; a nucleotide sequence having a length of 30 consecutive nucleotides, which begins at any nucleotide between nucleotide numbers 1371 to 1386, or 1431 to 1447 of the nucleotide sequence of SEQ ID NO: 2, and terminates at any nucleotide between nucleotide numbers 1400 to 1415, or 1460 to 1476 of the nucleotide sequence of SEQ ID NO: 2, respectively; and a nucleotide sequence having a length of 20 consecutive nucleotides, which begins at the nucleotide of nucleotide number 1435 of the nucleotide sequence of SEQ ID NO: 2, and terminates at the nucleotide of nucleotide number 1454 of the nucleotide sequence of SEQ ID NO: 2; and (7) a nucleotide sequence which is complementary to any of the nucleotide sequences as defined in (5) or (6).
