摘要

编码载铁蛋白H亚基的人类基因属于一个复杂的多基因家族,由表达基因和数量不明的假基因组成。我们使用了一种基于PCR的策略,从人类基因组DNA样本中特异性扩增H假基因。用这种方法克隆了三个新的H假基因,并通过DNA序列分析对其进行了鉴定。此外,我们还发现了一种新的伪基因,其大小(700 bp)是由假定编码区的多个检测事件引起的。

PCR analysis of the H ferritin multigene family reveals the existence of two classes of processed pseudogenes.

The human gene coding for the apoferritin H subunit belongs to a complex multigene family constituted by the expressed gene and by an undefined number of pseudogenes. We have used a strategy based on PCR to amplify specifically the H pseudogenes from a sample of human genomic DNA. With this approach, three new H pseudogenes have been cloned and characterized by DNA sequence analysis. In addition, we have identified a new type of pseudogene, the size of which (700 bp) is caused by multiple detection events in the putative coding region.
