Parent parasite used to introduce the genetic modification
Rodent Malaria ParasiteP. berghei
Parent strain/lineP. berghei ANKA
Name parent line/clone P. berghei ANKA 1037m1f1mocl1 (RMgm-32)
Other information parent lineP. berghei ANKA 1037m1f1mocl1 (1037cl1; RMgm-32) is a reference ANKA mutant line which expresses GFP-luciferase under control of a schizont-specific promoter (PubMed: PMID: 20019192). It does not contain a drug-selectable marker and has been selected by FACS sorting based on GFP expression

Additional remarks genetic modificationName of unsuccessful attempts: exp. 1156
The gene has been targeted for disruption/deletion using a construct for targeted gene disruption by double cross-over homologous recombination. The primers of the two target sequences of the gene are provided below.
The unsuccessful attempt to disrupt the gene might indicate an essential function during asexual blood stage development.
The gene has been selected for targeted gene disruption based on its presence in a proteome of membranes of infected red blood cells.
