短散布重复DNA序列(西内斯)是所有哺乳动物基因组中分散重复DNA的主要组成部分(参见参考文献1-6)。大多数西内斯含有一个基因内RNA聚合酶III启动子,该启动子在重复DNA序列的5′端启动转录7 -9,并且已经提出通过RNA中间体机制促进这些序列的转座和扩增10,11。我们已经发现了几个SINE家族在原猴纲Galago crassicaudatus有启动子区类似于转移RNA基因12,13。为了确定Galago西内斯与哺乳动物tRNA基因之间的关系,我们比较了它们的序列。在这里,我们证明Galago单体和II型SINE家族12分别与人甲硫氨酸tRNA基因14具有68%和62%的同源性。我们已经将我们的分析扩展到包括大鼠identifier 15和小鼠B2(参考文献16)家族,并表明它们的序列分别与丙氨酸和丝氨酸tRNA基因密切相关。我们的观察表明,许多哺乳动物的SINE家族扩增的tRNA假基因。
Short interspersed repetitive DNA sequences (SINEs) are the major component of dispersed repetitive DNA in all mammalian genomes (see refs 1–6 for reviews). Most SINEs contain an intragenic RNA polymerase III promoter that initiates transcription at the 5′ end of the repeated DNA sequence7–9 and which has been proposed to facilitate the transposition and amplification of these sequences by an RNA-intermediate mechanism10,11. We have discovered several SINE families in the prosimian Galago crassicaudatus which have promoter regions similar to transfer RNA genes12,13. To determine the relationship between Galago SINEs and mammalian tRNA genes, we have compared their sequences. Here, we demonstrate that the Galago monomer and type II SINE families12 are 68 and 62% homologous, respectively, with a human methionine tRNA gene14. We have extended our analysis to include the rat identifier15 and mouse B2 (ref. 16) families and show that their sequences are closely related to alanine and serine tRNA genes, respectively. Our observations suggest that many mammalian SINE families are amplified tRNA pseudogenes.
