| Name of the mutant parasite | |
| RMgm number | RMgm-524 |
| Principal name | K13 pk7 |
| Alternative name | |
| Standardized name | |
| Is the mutant parasite cloned after genetic modification | Yes |
| top of page | |
| Phenotype | |
| Asexual blood stage | Not different from wild type |
| Gametocyte/Gamete | Not different from wild type |
| Fertilization and ookinete | Ookinete numbers (in vitro) reduced to 9% of wild type |
| Oocyst | Oocyst numbers (day 12-14) reduced to 9% of wild type. The remaining oocyst are growth arrested from about day 9 |
| Sporozoite | no sporozoites |
| Liver stage | Not tested |
| Additional remarks phenotype | The gene has been targeted for gene deletion using a construct aimed at integration into the genome by double cross-over homologous recombination The gene has been targeted for disruption in a 'kinome-wide' study for deletion of genes encoding Plasmodium protein kinases (protein kinase-like proteins). See the paper for additional information on the analysis of the phenotype. Disruption of the P. falciparum ortholog has been attempted (Solyakov et al., 2011, Nat Commun, 2:565). After transfection with a KO vector a strong PCR signal diagnostic for gene disruption was observed in transfected populations indicating that this gene is not essential for asexual proliferation. Cloning will however be required to validate this interpretation for this |
