Polypyrimidine tract-binding protein interacts with the 3' stem-loop region of Japanese encephalitis virus negative-strand RNA.
Virus Res. 2006 Feb; 115(2):131-40.VR

Abstract

The 3' stem-loop (SL) region of positive- and negative-strand RNA of Japanese encephalitis virus (JEV), like that of other flaviviruses, may function as cis-acting signals during RNA replication. In order to demonstrate the specific interaction between JEV 3' SL regions and BHK-21 cellular proteins, we performed gel mobility shift assay and UV-induced cross-linking assay. We identified seven cellular proteins of 110, 87, 67, 45, 38, 34, and 30 kDa that bound to the (+)3' SL RNA, and eight cellular proteins of 138, 110, 87, 67, 55, 52, 38, and 34 kDa that bound to the (-)3' SL RNA. The 55 kDa protein was identified as the polypyrimidine tract-binding (PTB) protein by immunoprecipitation assay. These data suggest that the 3' SL regions of JEV-RNA of both polarities may act as recruiting signals for the components of viral replication complexes including host cell-derived PTB protein.
