The tobacco mosaic virus (TMV) replicase complex contains virus- and host-encoded proteins. In tomato, one of these host proteins was reported previously to be related serologically to the GCD10 subunit of yeast eIF-3. The yeast two-hybrid system has now been used to show that yeast GCD10 interacts selectively with the methyltransferase domain shared by the 126 and 183 kDa TMV replicase proteins. These findings are consistent with a role for a GCD10-like protein in the TMV replicase complex and suggest that, in TMV-infected cells, the machinery of virus replication and protein synthesis may be closely connected.
