Vaccinia virus morphogenesis: a13 phosphoprotein is required for assembly of mature virions.

Journal of virology - 1 Aug 2004

Unger Bethany, Traktman Paula

Abstract excerpt

The 70-amino-acid A13L protein is a component of the vaccinia virus membrane. We demonstrate here that the protein is expressed at late times of infection, undergoes phosphorylation at a serine residue(s), and becomes encapsidated in a monomeric form. Phosphorylation is dependent on Ser40, which lies within the proline-rich motif SPPP. Because phosphorylation of the A13 protein is only minimally affected by...
