SV40 PolyA (Simian virus 40 PolyA, also called PolyA) sequence is DNA sequence (240 bp) that possesses the activity of transcription termination and can add PolyA tail to mRNA. PolyA contains AATAAA hexanucleotide polyadenylation signal.

The SV40 polyA is a region of the SV40 (Simian virus 40) genome where transcripts coming from both directions terminate. Hence, it functions as a transcription terminator and poly A signal in either orientation. Part ID O1JXRV Name SV40 polyA signal

pCAGGS plasmid can be used to express gene efficiently under the control of chicken b- actin, rabbit b- globulin heterozygous promoter (CAG), and human CMV-IE enhancer in various mammalian cells. The CAG promoter sequence is part of the chicken b- actin promoter, the first exon and the first intron (it seems to have strong enhanced subtype activity.

Out of those listed, the SV40 late polyA and rbGlob polyA are thought to be more efficient in terminating transcription due to the presence of additional helper sequences (2-3). As alluded to above, termination and polyadenylation of Polymerase II transcripts (and therefore mRNAs) are coordinated processes.

In vitro and cell culture studies indicate that plasmids containing the SV40 and the synthetic poly A sequences present significant improvements in nuclease resistance (up to two-fold increase in half-life). However, RT-PCR analysis demonstrated that significant reduction in mRNA steady-state levels … Out of those listed, the SV40 late polyA and rbGlob polyA are thought to be more efficient in terminating transcription due to the presence of additional helper sequences (2-3).

From Wikipedia, the free encyclopedia SV40 is an abbreviation for simian vacuolating virus 40 or simian virus 40, a polyomavirus that is found in both monkeys and humans. Like other polyomaviruses, SV40 is a DNA virus that has the potential to cause tumors in animals, but most often persists as a latent infection. The SV40 polyA is a region of the SV40 (Simian virus 40) genome where transcripts coming from both directions terminate.
