通过对BALB/c小鼠主要组织相容性复合体(MHC)的染色体行走,我们在分子水平上将K区与I区联系起来。49个重叠的cosmid克隆定义了一段约600 kb的DNA,包含2个I类基因和7个II类基因。通过多态性限制性内切位点的Southern blot分析,在K区和I区标记位点之间定位了11个独立的重组事件。在这些事件中,有8个涉及到在卡斯泰尼小家鼠和实验室小鼠品系的基因之间以异常高的0.6%-1.50/b的频率进行交叉,并且它们被限制在两个小的DNA片段中。我们的结论是,重组热点存在于这些位置上的两个Mm castaneus MHC单倍型测试。相比之下,实验室小鼠的几种MHC单倍型似乎缺乏这些热点。
By chromosome walking in the major histocompatibility complex (MHC) of the BALB/c mouse, we have linked the K region to the I region at the molecular level. Forty-nine overlapping cosmid clones define a stretch of about 600 kb of DNA containing 2 class I and 7 class II genes. Eleven independent recombination events were mapped between the K and the I region marker loci by Southern blot analysis of polymorphic restriction sites. Eight of these events involved crossing-over, at an unusually high frequency of 0.6%-1.50/b, between genes from Mus musculus castaneus and laboratory mouse strains, and they were confined to two small stretches of DNA. We conclude that recombination hotspots are present at these positions in the two Mm castaneus MHC haplotypes tested. In contrast, several MHC haplotypes of laboratory mice appear to lack those hotspots.
