S. Longacre et al., PLASMODIUM-VIVAX MEROZOITE SURFACE PROTEIN-1 C-TERMINAL RECOMBINANT PROTEINS IN BACULOVIRUS, Molecular and biochemical parasitology, 64(2), 1994, pp. 191-205
Recombinant proteins derived from the Plasmodium vivax merozoite surfa
ce protein 1 have been produced in the baculovirus expression system.
These proteins correspond approximately to the Plasmodium vivax analog
s of the 42-kDa or 19-kDa C-terminal processing products previously de
scribed for Plasmodium falciparum. Each was produced in two versions,
either as a membrane-bound entity located on the cell surface and prob
ably carrying a glycosylphosphatidylinositol addition, or as a secrete
d entity lacking a membrane anchor. Many native conformational epitope
s appear to be accurately reproduced in these molecules. Both the 42-k
Da and 19-kDa analogs an be N-glycosylated in the baculovirus system a
nd the N-glycosylation appears to be necessary for efficient secretion
of both the 42-kDa and 19-kDa recombinant proteins.
