Papaya ringspot virus (PRSV) is a pathogenic plant virus in the genus Potyvirus and the virus family Potyviridae which primarily infects the papaya tree. This gene is a protein that makes up part of the coat of the virus, and when a plant contains this gene in its own cells, it is immune to the effects of the virus.

Nucleotide sequence of the capsid protein gene and 3 non-coding region of papaya mosaic virus RNA. We show that PapMV-CP-M2e virus-like particles (VLPs) can induce production in mice of anti-M2e antibodies that can recognize influenza-infected cells. PapMV nanoparticles can also serve as a vaccine platform as they can increase the immune response to fused peptide antigens. Capsid protein mutants that affect encapsidation and/or movement usually cannot, however, be efficiently recovered from plants.
