Hepatitis B virus PRE beta
- Hepatitis B virus PRE beta
The Hepatitis B virus PREbeta (HBV PREbeta) is an RNA structure that is shown to play a role in nuclear export of HBV mRNAs.
The minimal HBV PREbeta structure consists of a 23 nt stem-loop, with a 9 nt apical loop. The conserved stem-loop was predicted within the HBV PRE sequence and confirmed by mutagenesis. [cite journal| title= The hepatitis B virus post-transcriptional regulatory element contains two conserved RNA stem-loops which are required for function | id = PMID 9776740] .The Rfam structure is based on a covariation model.
