在真核细胞基因组中发现一类新内含子——AT-AC内含子, 除结构特征与普遍存在的核mRNA前体内含子有明显不同外,剪接机制上也存在一定差异.文章介绍了该内含子的分布,结构特征及剪接机理,并与主内含子作了相应比较.
A new class of introns that possess AT and AC respectively at their 5' and 3' ends, has been identified in eukaryotic genome. The AT-AC introns differ from the major class of pre-mRNA introns both in structural features and in splicing mechanism. The distribution, structural features and splicing mechanism of AT-AC introns are discussed and compared with major class of introns.
