The 3'NCR of the SHFV negative-strand RNA [SHFV 3'(-)NCR RNA] is thought to be the initiation site of full-length and possibly also subgenomic positive-strand RNA and so is likely to contain cis-acting signals for viral RNA replication. Cellular and viral proteins may specifically interact with this region to form replication complexes. When in vitro transcribed SHFV 3'(-)NCR RNA was used as a probe in gel mobility shift assays, two RNA-protein complexes were detected with MA104 S100 cytoplasmic extracts. The specificity of thes RNA-protein interactions was demonstrated by competition gel mobility shift assays. Four MA104 protein (103, 86, 55, and 36 kDa) were detected by UV-induced cross-linking assays and three proteins (103, 55, and 36 kDa) were detected by northwestern blotting assays. The binding sites for these proteins were mapped to the region between nucleotides 117 to 184 on the SHFV 3'(-)NCR RNA. Four cellular proteins with identical molecular masses to those of the proteins that bind to the SHFV 3'(-)NCR RNA were detected by the 3'(-)NCR of another arterivirus, LDV-C, suggesting that divergent arteriviruses utilize the same set of conserved cell protein domains.
