The following genetic modifications were attempted Gene disruption
Number of attempts to introduce the genetic modification Unknown
Reference (PubMed-PMID number) Reference 1 (PMID number) : 29138437
Parent parasite used to introduce the genetic modification
Rodent Malaria ParasiteP. berghei
Parent strain/lineP. berghei ANKA
Name parent line/clone P. berghei ANKA 507cl1 (RMgm-7)
Other information parent lineP.berghei ANKA 507cl1 (RMgm-7) is a reference ANKA mutant line which expresses GFP under control of a constitutive promoter. This reference line does not contain a drug-selectable marker (PubMed: PMID: 16242190).

Additional remarks partial/complete disruption
Selectable marker used to select the mutant parasitetgdhfr
Promoter of the selectable markerunknown

Selection (negative) procedureNo
Additional remarks genetic modificationThe unsuccessful attempts to disrupt this gene indicate an essential function during asexual blood stage growth.
In the paper evidence is presented that
i)PhIL1 is part of the inner membrane complex (IMC).
ii) PhIL1 is located in the IMC in all three invasive (merozoite, ookinete-, and sporozoite) stages of development, as well as in the male gametocyte and locates both at the apical and basal ends of ookinete and sporozoite stages
