The human retinoblastoma cell line Y79 has multiple copies of the MYCN gene and the DEAD box gene DDXI. Both genes have been mapped to chromosome band 2p24. A third gene, encoding the alpha-subunit of mitochondrial ATP synthase (ATPSA), is also amplified in Y79. Here we report that there are at least four human mitochondrial ATPSA-related genes located on four different chromosomes. The ATPSA gene that is amplified in Y79 originates from chromosome 18. In Y79, the amplified copies of both the ATPSA and the MYCN genes are located on a homogeneously staining region (HSR) at chromosome band Ip34.
人视网膜母细胞瘤细胞系Y79含有多个MYCN基因拷贝和DEAD框基因DDXI。这两个基因都已定位到染色体2p24带。第三个基因,编码线粒体ATP合酶(ATPSA)的α亚基,在Y79中也有扩增。在此我们报告,至少有四个与人类线粒体ATPSA相关的基因位于四条不同的染色体上。在Y79中扩增的ATPSA基因起源于18号染色体。在Y79中,ATPSA和MYCN基因的扩增拷贝都位于染色体1p34带的一个均匀染色区(HSR)上。
