SV40 polyA信号序列的作用主要体现在两个方面:一是诱导mRNA的切割,二是促进mRNA的聚腺苷酸化。在真核生物细胞中,mRNA需要经过切割和聚腺苷酸化的过程才能够成熟。SV40 polyA信号序列的存在可以提高mRNA的稳定性和翻译效率,从而影响基因的表达水平。 对于SV40 polyA信号序列的研究,科学家们也发现了一些与基因调控相关的...
We describe the pA regulator, an RNA-based switch that controls mammalian gene expression through modulation of a synthetic polyA signal (PAS) cleavage introduced into the 5′ UTR of a transgene. The cleavage is modulated by a 'dual-mechanism'—(1) aptamer clamping to inhibit PAS cleavage and...
Here we report on the design of a splicing based lentiviral platform that combines a polII promoter for minimized toxicity and cell specific expression, shRNAs derived from intron based pre-microRNA, exon based protein expression, a modified polyA signal for minimal downstream effects and 3rd ...

Method and apparatus for maintaining optical signal having low degree of polarization inspecific state of polyarizationAn optical circuit includes a light source having a low degree of polarization, an input section connected to the light source, and an output section connected to the input section....
1) polyadenylation signal 加polyA信号 补充资料:超声信号的加权 超声信号的加权 超声学术语。 超声检查中,对获得的信号进行变换,突出信号中的某些部分,抑制信号中的另一些部分的处理方法。方法是将信号中的不同部分乘以不同的权数。滤波就是加权的一个例子,其作用是突出信号中的一些频率成分;抑制另一些频率成分,又...
