No effect seen on asexuals, but incomplete knockdown. \"In this study, we demonstrate that the presence of PfWLP1 is crucial for both the stability of these gametocyte-specific adhesion complexes as well as for gametocyte maturation and gametogenesis. Using reverse genetics, we generated a PfWLP1-knockdown parasite line for functional characterization of the protein. Knockdown of PfWLP1 resulted in a slight reduction of gametocyte numbers and significantly the impaired ability of the gametocytes to exflagellate. PfWLP1-knockdown further led to reduced protein levels of the Limulus coagulation factor C-like (LCCL)-domain proteins PfCCp1 and PfCCp2, which are key components of the adhesion complexes. These findings suggest that the interaction of PfWLP1 with members of the PfCCp-based adhesion complex ensures complex stability and thereby contributes to gametocyte viability and exflagellation.\"

Imaging data (from Malaria Metabolic Pathways)

PfWLP1 is expressed in the asexual blood stages of Plasmodium falciparum. a Expression of PfWLP1 in the asexual blood stages. PfWLP1 was immunolabelled with anti-PfWLP1-rp2 antisera (green); the asexual blood stages were visualized with antisera against PfEXP1, PfAMA1 and PfMSP1 (red). The parasite nuclei were highlighted by Hoechst nuclear stain (blue). ImSchizont, immature schizont; mSchizont, mature schizont. Bar 5 μm. Data are representative of five independent experiments each.von Bohl A, Kuehn A, Simon N, Ngongang VN, Spehr M, Baumeister S, Przyborski JM, Fischer R, Pradel G.
