No immediate clinical relevance; leaves open minimal RNA motifs as tools for multimerization and antiviral research.
The 75-base RNA segment (bases 23-97) of phi29 pRNA is an independent domain responsible for RNA/RNA interaction and procapsid binding, serving as a model for RNA dimerization studies.
Chen et al. (1999) studied this question. RNA segment 23-97 was evaluated on RNA dimerization, hexamer formation, and phi29 assembly inhibition. A 75-base RNA segment (bases 23-97) formed dimers, interlocked into hexamers, and inhibited phi29 assembly in vitro, acting as an independent domain for RNA/RNA interaction.
