作为酵母人工染色体(YAC)克隆的哺乳动物DNA片段,当置于适当的酵母遗传背景中时,可以通过DNA介导的转化进行操纵。通过同源重组的方法,将酵母端粒和选择性标记引入到人来源的YAC中,删除重组位点附近的所有序列,构建了一种“片段载体”。该方法的一个强大的应用是使用人类Alu家族重复序列来将重组靶向于人类来源的YAC上的多个独立的位点。这一过程产生的一组缺失导数极大地促进了大基因组片段的限制图谱。与单拷贝序列的靶向重组,如cDNA,将有许多额外的应用。这种方法为克隆为YAC的哺乳动物DNA片段的操作和表征建立了一个范例。
Mammalian DNA segments cloned as yeast artificial chromosomes (YACs) can be manipulated by DNA-mediated transformation when placed in an appropriate yeast genetic background. A "fragmenting vector" has been developed that can introduce a yeast telomere and selectable marker into human-derived YACs at specific sites by means of homologous recombination, deleting all sequences distal to the recombination site. A powerful application of the method uses a human Alu family repeat sequence to target recombination to multiple independent sites on a human-derived YAC. Sets of deletion derivatives generated by this procedure greatly facilitate restriction mapping of large genomic segments. Targeting recombination with single copy sequences, such as cDNAs, will have many additional applications. This approach establishes a paradigm for manipulation and characterization of mammalian DNA segments cloned as YACs.
