Pv12, a 6-Cys antigen of Plasmodium vivax, is localized to the merozoite rhoptry
Pf12 in Plasmodium falciparum has been characterized as a merozoite surface protein and the Pf12 gene is actively transcribed during schizont stage. An orthologous gene, Pv12, has been identified in genome of P. vivax, but the protein product has not been characterized. The Pv12 is a 362 amino acid...
