abstract = {Transmission of the malaria parasite Plasmodium to
mosquitoes necessitates gamete egress from red blood cells
to allow zygote formation and ookinete motility to enable
penetration of the midgut epithelium. Both processes are
dependent on the secretion of proteins from distinct sets of
specialized vesicles. Inhibiting some of these proteins has
shown potential for blocking parasite transmission to the
mosquito. To identify new transmission blocking vaccine
candidates, we aimed to define the microneme content from
ookinetes of the rodent model organism Plasmodium berghei
using APEX2-mediated rapid proximity-dependent
biotinylation. Besides known proteins of ookinete
micronemes, this identified over 50 novel candidates and
sharpened the list of a previous survey based on subcellular
fractionation. Functional analysis of a first candidate
uncovered a dual role for this membrane protein in male
gametogenesis and ookinete midgut traversal. Mutation of a
putative trafficking motif in the C-terminus affected
ookinete to oocyst transition but not gamete formation. This
suggests the existence of distinct functional and transport
requirements for Plasmodium proteins in different parasite
stages.},
