Membrane synthesis, specific lipid requirements, and localized lipid composition changes associated with a positive-strand RNA virus RNA replication protein.

Abstract excerpt

Multifunctional RNA replication protein 1a of brome mosaic virus (BMV), a positive-strand RNA virus, localizes to the cytoplasmic face of endoplasmic reticulum (ER) membranes and induces ER lumenal spherules in which viral RNA synthesis occurs. We previously showed that BMV RNA replication in yeast is severely inhibited prior to negative-strand RNA synthesis by a single-amino-acid substitution in the ole1w allele...
