A cDNA library from the mink pituitary was screened using as probe a synthetic oligodeoxyribonucleotide, 5'-TTCATGACCTCCGA-3', corresponding to the endorphin region of bovine proopiomelanocortin (POMC) cDNA. As a result, several clones containing inserts complementary to POMC mRNA were identified. The sequence of one of the fragments (585 bp, 65% of the total length of mRNA) was determined. A high degree of homology (over 80%) among the primary structures of sequences from mink, man, and bovine cDNA POMC was established. With the cloned mink cDNA fragment as probe, the DNAs from mink-Chinese hamster hybrid clones were studied. The results of segregation analysis of mink POMC sequences and mink chromosomes in the mink-Chinese hamster panel allowed us to assign the POMC gene to mink chromosome 11.
使用与牛阿黑皮素原(POMC)cDNA的内啡肽区域相对应的合成寡脱氧核糖核苷酸5'-TTCATGACCTCCGA-3'作为探针,筛选水貂垂体的cDNA文库。结果,鉴定出了几个含有与POMC mRNA互补插入片段的克隆。测定了其中一个片段的序列(585 bp,占mRNA全长的65%)。水貂、人和牛cDNA POMC序列的一级结构之间建立了高度同源性(超过80%)。以克隆的水貂cDNA片段为探针,研究了水貂-中国仓鼠杂交克隆的DNA。在水貂-中国仓鼠细胞系中对水貂POMC序列和水貂染色体进行分离分析的结果使我们能够将POMC基因定位到水貂的11号染色体上。
