对编码蛔虫U小核RNA(snRNA)的几个基因进行了鉴定。除了U6(由RNA聚合酶III转录)和U2假基因(不转录)之外,所有基因在体外都由RNA聚合酶II主动转录。通过对秀丽隐杆线虫U snRNA基因5′端侧翼序列的比较,发现每个编码序列的上游都有一个保守序列。西娅所表征的蚯蚓snRNA与其他高等真核生物的snRNA非常相似。没有证据表明任何snRNA存在反式剪接特异性变体。这表明顺式和反式剪接体都是由同一个snRNP(核糖核蛋白)库形成的。
Several genes encodingAscaris lumbricoidesU small nuclear RNAs (snRNAs) were characterized. With the exception of U6 (transcribed by RNA pol III) and the U2 pseudogenes (not transcribed) all of the genes are actively transcribed by RNA polymerase IIin vitro. A comparison of 5′ flanking sequences of U snRNA genes inCaenorhabditis elegansrevealed a conserved sequence upstream of each coding sequence. TheA. lumbricoidesU snRNAs characterized were quite similar to snRNAs of other higher eukaryotes. There was no evidence to suggest the existence oftrans-splicing-specific variants for any snRNA. It is suggested that bothcis- andtrans-spliceosomes are formed from the same pool of snRNPs (ribonucleoproteins).
