The Heron HBV RNA encapsidation signal epsilon is an RNA structure that is shown to facilitate encapsidation of the pregenomic RNA required for replication.

The HHBV epsilon consists of a stem structure, a bulge and an apical stem-loop. The RNA structure has been determined by chemical probing and by mutagenesis [1]. A recent NMR analysis of the HHBV epsilon have shown that the apical loop to be capped by a stable well-structured UGUU tetraloop [2].

The Rfam structure is based on a covariation model.
