The introns of animal nuclear genes and of viral genes encoding protein possess at their 3' splice-site the consensus sequence (CT)11NTCAG (Mount, S.M. (1982) Nucl. Acids Res. 10, 459-472; Green, M.R. (1986) Ann. Rev. Genet. 20, 671-708). However, the total 39 introns of the 5 imported mitochondrial proteins of higher eucaryotes whose gene structure has been determined to date show a predominance of 44% for base T at position -4. Apparently, a variant consensus sequence, i.e. (CT)11TTCAG, characterizes the genes of nuclear encoded mitochondrial proteins.
动物核基因以及编码蛋白质的病毒基因的内含子在其3'剪接位点具有共有序列(CT)11NTCAG(蒙特,S.M.(1982年)《核酸研究》10,459 - 472;格林,M.R.(1986年)《遗传学年度评论》20,671 - 708)。然而,迄今为止已确定基因结构的高等真核生物5种导入线粒体蛋白的总共39个内含子在 - 4位置碱基T占比达44%。显然,一种变异的共有序列,即(CT)11TTCAG,是核编码线粒体蛋白基因的特征。
