Part:BBa_K313010

loading sequence of RNA phage MS2

This sequence is necessary for loading of RNA into the capsid of RNA phage MS2. The coat proteins of phage MS2 is known to aggregate around this sequence.

Please see [http://2010.igem.org/Team:UT-Tokyo/Sudoku_assay_MS2 Phage MS2] assay page.

We are SYSU-CHINA 2021 and this year we use circRNA to colocalize enzymes, which are fused to RNA binding proteins(RBP). We choose MS2 coat protein and PP7 coat protein as our RBP,and their aptamer on circRNA.For contribution, we predict its 2D and 3D structure,to present a visual impression.

We use RNAfold and StructureEditor to predict 2D structure of our circRNA, which contains MS2 aptamer.The results are below:

We use this website:http://biophy.hust.edu.cn/new/3dRNA/create, to predict the 3D structure of our circRNA, which contains MS2 aptamer.The result lists below:

We are SYSU-CHINA,and this year we use this part as MS2 coat protein's aptamer to do a split EGFP experiment,for the proof of concept.Here we found a research article, which use liner RNA with MS2 and PP7 aptamer, to do the split EGFP experiment.Below are their experimental data.
