EV71 (enterovirus 71) RNA contains an internal ribosomal entry site (IRES) that
directs cap-independent initiation of translation. IRES-dependent translation
requires the host's translation initiation factors and IRES-associated
trans-acting factors (ITAFs). We reported recently that mRNA decay factor AUF1 is
a negative-acting ITAF that binds IRES stem-loop II. We also reported that the
small RNA-processing enzyme Dicer produces at least four small RNAs (vsRNAs) from
the EV71 IRES. One of these, vsRNA1, derived from IRES stem-loop II, reduces IRES
activity and virus replication. Since its mechanism of action is unknown, we
hypothesized that it might control association of ITAFs with the IRES. Here, we
identified the mRNA stability factor HuR and the RISC subunit Argonaute 2 (Ago2)
as two ITAFs that bind stem-loop II. In contrast to AUF1, HuR and Ago2 promote
EV71 IRES activity and virus replication. In vitro RNA-binding assays revealed
that vsRNA1 can alter association of Ago2, HuR, and AUF1 with stem-loop II. This
presents a possible mechanism by which vsRNA1 could control viral translation and
replication.
