And several clones were obtained from a cDNA library derived from the hypothalamus. Next, colony hybridization was carried out using the cDNA fragment inserted into the previously isolated clone (FERM P-16572) as a probe to obtain a positive clone. This clone was deposited with the Institute of Biotechnology and Industrial Technology, National Institute of Advanced Industrial Science and Technology.
- Plasmid DNA was prepared using Qiaprep Midi Kit (Qiagen), and the entire nucleotide sequence was determined by the shotgun method (Sambrook et al., Molecular Cloning: A laboratory manual 2nd edn., (1989)). The fragmented DNA was fractionated by 2% agarose low melting gel electrophoresis using Biolab Yuichi (Tosho Denki Co., Ltd.) using a closed ultrasonic biological material processing device.
- the fragment was purified with a gene clean spin kit (Mol01), blunt-ended with T4 DNA polymerase (Takara Shuzo), and cloned into HincI I / BAP-treated pUC118 vector.
- XL1-Blue was used as a host, and transformation was performed with E. coli pulsar (Bio-Rad).
- the obtained shotgun clones were sequenced using Dye Primer Cycle Sequencing Kit FS (PerkinElmer) or Die Yu Mine One Night Cycle Sequencing Kit FS (PerkinElmer). The obtained sequence was combined and edited with DNA sequencing software, Sequencia (Hitachi Software), and the entire nucleotide sequence was determined.
- the entire nucleotide sequence was found to be 2700 bp and encode a protein consisting of 413 amino acids (SEQ ID NO: 5). Due to the presence of a stop codon 5 'to the open' reading 'frame, this cDNA is considered to include the entire coding region (SEQ ID NO: 2). When this sequence was translated into an amino acid sequence, the first, second, third, fourth, fifth, sixth and seventh transmembrane regions were identified on the hydrophobicity plot (FIG. 1).
- the size of the open reading frame was about 1.2 kb, which was comparable to that of the known G protein-coupled receptor Yuichi protein.
- the G protein-coupled receptor protein has some commonality in its amino acid sequence and forms one protein family. A homologous search was performed using the amino acid sequence encoded by the isolated cDNA, and a muscarinic acetylacetylcholine receptor, a known G protein-coupled receptor protein, was identified as M3. Evening protein (Lee, PH et al., Biochim. Biophys. Acta 1223, 151-154 (1994)), human muscarinic acetylcholine receptor Yuichi M5 protein (Bonner, T. I.
- the resulting phage clone was digested with Sacl, and three bands of one clone were subcloned. These were named II (SEQ ID NO: 11), 13 (SEQ ID NO: 12), and 15 (SEQ ID NO: 13), respectively. The sequences of these fragments were determined, and the hypothetical sequence was examined by comparison with a rat homolog.
- PCR products were named probe 2 and probe 3, respectively. They were seeded in plates at a concentration of human hypothalamic cDNA (1.3xl0 6 phage) 150 ⁇ plates per Ri 5.6xl0 4. The obtained subpool was checked by PCR using primers YS03 and YS05. One positive subpool was screened using probe 2 in the same manner as in the screening of the genomic library. As a result, one cDNA clone containing 5, UTR was obtained from TM5 and named cDNA clone 1.
- cDNA clone 1 was digested with SacI I and the 3.3 kb band containing the vector and 5 'end region was treated with shrimp alkaline phosphatase.
- cDNA clone 2 was also digested with SacII and the 1.7 kb fragment was ligated to the 3.3 kb fragment from cDNA clone 1. The clone into which the ligated fragment was inserted was deposited at the National Institute of Biotechnology and Industrial Technology.
- BG2 protein is a known G protein-coupled receptor protein, human Yukihi-2C-1 adrenocept (Regan, JW et al., Proc. Natl. Acad. Scad. USA 85, 6301). -6305 (1988)), adrenocept Yuichi from mouse (Jasper JR et al., Biochem. Biophys. Acta 1178, 307-309 (1993)), human muscarinic acetylcholine receptor Yuichi M3 (Peralta, EG et al. al., EMBO J. 6, 3923-3929 (1987)) and 32 to 28, respectively, with a homology of 27%.
- pro portion 4 In the detection of the human "BG2", pro portion 4 a 32 P ⁇ -dCTP (Amershajn, Prime It II) And used as a cDNA probe. Further, as a plotting membrane, an MTN (Human Multiple Tissue Northern) blot (Clontech) was used. After prehybridization at 68 ° C for 30 minutes in ExpressHyb solution (Clontech), the probe was hybridized to the membrane at 68 ° C for 1 hour (final probe concentration was 1.5xlO s cpm / ml) ).
