M. Ito et al., ROLE OF A SINGLE AMINO-ACID AT THE AMINO-TERMINUS OF THE SIMIAN-VIRUS-5 F2 SUBUNIT IN SYNCYTIUM FORMATION, Journal of virology, 71(12), 1997, pp. 9855-9858
The fusion (F) protein of simian virus 5 (strain W3A) induced extensiv
e cell fusion in BHK cells when expressed alone, while that of strain
WR did not. Mutational analysis demonstrated that the fusing activity
can be transferred to the WR F protein by a proline residue at positio
n 22 of subunit W3A F2.
