Mutations in the 5' noncoding sequence of the Sabin strain of type 1 poliovirus revealed that specific loci, such as positions 551 to 563, play an essential role in viral replication.
Specific loci within the 5' noncoding sequence of the poliovirus genome are essential for viral replication and may interact to form functional structures.

Hypothesis-generating for live-attenuated polio vaccine design; leaves open clinical validation in human models.
Kuge et al. (1987) studied Poliovirus replication. Deletion and insertion mutations in the 5' noncoding sequence vs. Wild-type Sabin strain was evaluated on Viability and plaque size of mutant viruses. Mutations in the 5' noncoding sequence of the Sabin strain of type 1 poliovirus revealed that specific loci, such as positions 551 to 563, play an essential role in viral replication.
