The Gammaretrovirus core encapsidation signal is an RNA element known to be essential for stable dimerisation and efficient genome packaging during virus assembly.[1] Dimerisation of the viral RNA genomes is proposed to act as an RNA conformational switch which exposes conserved UCUG elements and enables efficient genome encapsidation.[2] The structure of this element is composed of three stem-loops. Two of the stem-loops called SL-C and SL-D form a single co-axial extend helix.
