C2 3

Each unique RNA dependent RNA polymerase (RdRP) initiates de novo replication of a RNA strand by interacting with RdRP-specific RNA sequences, henceforth called RdRP/RNA promoters. Please refer to Section: RdRP function for further details. The RdRP chosen for our project is taken from the Hepatitis C virus (HCV). The C2 RNA promoter was identified as such by Heinz, Kao (2000) , along with a number of other sequences. All of them possess a few common characteristics: an initiation cytidylate at the 3’ end, where the replication starts; and a stable secondary structure- single stranded tail and a stem of various length. Replication stops at the 5’ end.

Usage

Used as an RNA promoter to direct replication by RdRP.

RdRP-directed Replication

1. The DNA strand gets transcribed and then translated, whereby the RdRP protein is produced. 2. The active RdRP binds to the 3’ end of the transcribed plus –sense RNA strand. It produces its complementary minus-sense RNA strand. 3. The RdRP interacts with the 5’ end of the replicated minus-sense RNA strand. It produces the plus-sense RNA strand again and completes the full replication of the RNA. The new RNA strand can act as a template as well and the process of replication can start over.
