top of page | |
Phenotype | |
Asexual blood stage | Not different from wild type |
Gametocyte/Gamete | Expression in gametocytes (speckled appearance). Following activation of female gametocytes, PAT::GFP to distribute towards the plasma membrane (reminiscent of osmiophilic bodies). |
Fertilization and ookinete | Expression in ookinetes (speckled appearance) |
Oocyst | Not tested |
Sporozoite | Expression in sporozoites, indicative for micronemal (and surface) location. Co-localisation of PAT with the micronemal protein TRAP in sporozoites. |
Liver stage | Late liver stage forms did not produce any fluorescent cells |
Additional remarks phenotype | Mutant/mutation A mutant lacking expression of PAT (Δpat; RMgm-1500); A mutant in which the endogeneous pat gene is replaced with the pat gene of P. falciparum 3D7: Δpat;pat(PF3D7)::mcherry; RMgm-1501) A mutant expressing GFP-tagged PAT and mCherry-tagged G377 (pat::gfp;g377:mcherry; RMgm-1503): A mutant lacking expression of PAT and expressing mCherry-tagged G377 (PBANKA_1463000) and a mutant lacking expression of PAT and expressing mCherry-tagged PPLP2 (PBANKA_1463000) A mutant expressing a GFP-tagged version of TRAP (ss::gfp::trap; RMgm-1505) A 'promoter-swap' mutant expressing PAT under the promoter of the ccp1/lap2 promoter (PBANKA_1300700)(patccp.PP; RMgm-1506) |

Additional remarks genetic modification | A 2417 bp product encompassing the entire ORF of pat (1626 bp) as well as 771 bp of the 5’UTR region was amplified from P. berghei genomic DNA with primers g1025 and g1027. The amplicon was cut with HincII and BamHI to release 1539 bp of the 3’ end of the ORF; this fragment was ligated into pLIS0010 (ΔNheI) containing the Toxoplasma dhfr/ts selection cassette to yield a C-terminal GFP fusion. The final plasmid pLIS0301 was digested with NheI, precipitated with 2.5 volumes ethanol and transfected into wildtype schizonts. | ||||||||||||||||||||||||||
