Implication
Hypothesis-generating for nsP3 as antiviral target in alphaviruses; further validation required before any clinical consideration.
Structured PICO
P
Population
Sindbis virus nsP3-coding region mutants (126 in conserved region, 23 in nonconserved region)
I
Intervention
Random linker insertion mutations in the nsP3-coding region
C
Comparator
Parental virus
O
Outcome
Temperature-sensitive (ts) plaque formation or significant differences in plaque morphologysurrogate
Mutations in the conserved region of the Sindbis virus nsP3 protein suggest it plays a critical role in the synthesis of viral minus-strand and subgenomic RNAs.
