초록

TAR (Transformation-Associated Recombination) cloning법은 복잡한 고등생물의 게놈으로부터 유전자나 특정 염색체 부위를 선별적 분리를 가능하게 한다. 이 방법은 목적으로 하는 염색체 부위의 주변에 존재하는 비교적 짧은 게놈 염기서열에 대한 정보를 필요로 한다. 이 기술은 출아효모의 spheroplasts 형질전환 동안 목적 유전자를 포함한 게놈 DNA와 그 유전자의 5' 또는 3' 말단 서열 (hook)을 포함하고 있는 TAR vector 사이에 일어나는 상동성 재조합에 의해 이루어진다. 본 연구에서는 TAR cloning 법을 상동성 유전자의 분리에 사용할 수 있는가를 조사하기 위해, 연간과 마우스 게놈의 HPRT 유전자를 선택하였다. 그 결과, 인간과 마우스의 게놈으로부터의 HPRT 유전자의 분리 빈도는 TAR vector로서 hHPRT hook 혹은 mHPRT hook을 사용한 경우에 거의 동일하게 나타났다. 또한 mHPRT 유전자의 gap 부분의 염기서열을 결정하여, 이 부분에 염기서열의 불안정의 요인이 되는 비정상적 특성을 발견하였다. 결론적으로 TAR cloning법을 이용하여 다른 이종 간의 게놈으로부터 상동성 유전자 즉 orthologue의 분리가 가능하였다. 더욱이 TAR cloning 시스템을 이용하여 고등동물 게놈 상에 남아있는 gap 부분을 메움으로서 고등동물의 모든 유전자들의 확인이 가속화될 수 있을 것으로 사료된다.

The transformation-associated recombination (TAR) cloning technique allows selective isolation of chromosome regions or genes from complex genome. The procedure requires knowledge of relatively small genomic sequences that reside adjacent to the chromosome region of interest. This method involves homologous recombination during spheroplast transformation between genomic DNA and a TAR vector that has 5' and 3' gene targeting sequences (hooks). To examine whether TAR cloning can be applied to the isolation of gene homologues, we chose the HPRT genes from human and mouse genome. As results, the yield of positive clones for HPRT gene from human and mouse genome when using a TAR vector containing mHPRT hook or hHPRT hook was almost same level. Analysis of the gap regions in mHPRT revealed that they contain abnormalities that could result in instability of the sequences. In conclusion, we were able to use the TAR cloning technology to isolate gene homologue (orthologue) from nonidentical genome. Moreover, the use of the TAR cloning system may accelerate work on closing the remaining gaps in mammalian genome to achieve the goal of annotation of all mammalian genes.
